All, According the WAS.The document says the worker process is managed by WAS .
But I found when typing w3wp /? There is a debug flag.
-debug
This option launches a worker process using the default
application host config file. By default, it will use
site id 1.
What does mean start worker process in debug mode? In what case we want to start a work process with debug option ? thanks.
Added
I didn't known why I got a exception when run w3wp.exe -debug.
ERROR: There has been an error during processing of this command.
Please check the event log and see if any errors or warnings have been
logged.
When I checked the log. It looks like:
The World Wide Web Publishing Service failed to set the application
pool for the application '/xxxx' in site '1'. The data field contains
the error number.
According to http://support.microsoft.com/kb/183480 it switches the security context of the running user which is not its normal mode of operation - I suppose this would make it easier to then attach a debugger and other utilities.

I see that airflow logs are stored at
base_log_folder/dag_id/task_id/date_time/1.log
i.e:
base_log_folder/dag_id={dag_id}/run_id={run_id}/task_id={task_id}/attempt={try_number}.log
Sometime my logs are huge and know its now a good idea to check them from the web ui, because the chrome cant handle so much size of logs.
I have access to the server and can check the logs.
So how can i break the longs into smaller files - v
i.e
{try_number}_1.log
{try_number}_2.log
{try_number}_3.log
...
Also noted that the log file {trynumber}.log, is only created when the task is completed.
while the task is running i can check the logs in the webui, but i dont see any file in the corresponding log folder.
So i need two things for logging from the server side:
break large log files into smaller files
see the log file live while the task is running, not only after the task is completed
In Airflow 2.4.0 there is an option to view full logs or only the first fragment thus huge logs are not loaded automatically:
Starting Airflow 2.5.0 the web UI also does auto tails for logs (PR)
Airflow does show live logs. If you will set for example a Sensor task that pokes resource you will see the poking attempts in the log when the task is running. It's important to note that there are local logs and remote logs (docs):
In the Airflow UI, remote logs take precedence over local logs when remote logging is enabled. If remote logs can not be found or accessed, local logs will be displayed. Note that logs are only sent to remote storage once a task is complete (including failure). In other words, remote logs for running tasks are unavailable (but local logs are available).
Huge logs are often a sign of not using log levels. If you have entries relevant for debugging then set DEBUG mode rather than INFO mode that way you can better control over the log size displayed in the UI using the AIRFLOW__LOGGING__LOGGING_LEVEL variable.
We have Websphere Message Broker v8.0.0.3 on Redhat Linux env, and we encounterd the following runtime error message:
BIP2057
Execution Group <insert_1> could not be started: broker name <insert_2>; UUID <insert_3>; label <insert_4>; Pub-Sub server <insert_5> (1=Yes, 0=No).
The situation is that one of the execution groups stopped (without any trace/log about it) and the wmb could not auto start with the BIP2057 error.
the weird part occurs when another EG restarted (unlinked reason to the first problem, because of some applicative errors) and then the first EG "took its place", started successfully, and now the second EG could not start for the same reason.
We have checked for user permissions or the logs without any success in identifying the problem.
Any help would be much appreciated.
Run the following service IBM MQSeries if it's not running already:
C:\Program Files (x86)\IBM\WebSphere MQ\bin\amqlsvc.exe
If it gives an
exception of Access Denied, your user must not be having rights to
log on.
Another possible resolution can be by restarting the
DataFlowEngine.exe process.
If none of the above scenarios fulfill the need, restart the system.
I'm having trouble hunting down an issue where an ASP.NET 4 application fails while trying to get user groups for a given user from time to time. The application pool associated with this application is setup to run under ApplicationPoolIdentity.
Exception Info
System.DirectoryServices.DirectoryServicesCOMException
HRESULT: 80072020
Message: An operations error occurred.
Extended Message: 000004DC: LdapErr: DSID-0C0906E8, comment: In order to perform this operation a successful bind must be completed on the connection., data 0, v1db1

System.DirectoryServices.DirectoryEntry.Bind()

System.DirectoryServices.DirectorySearcher.FindAll(Boolean)
System.DirectoryServices.DirectorySearcher.FindOne()
95%-99% of the time, this function works fine, but from time to time, it just starts failing. When I change the application pool to use LocalSystem or NetworkService, it starts working. When I change back to ApplicationPoolIdentity it begins failing again. The only way to get the site working again with ApplicationPoolIdentity is to reboot the server.
I was able to find a similar issue here, but the resolution was a reboot as well. I'd like to find a more permanent solution short of changing the identity of the application pool.
While a reboot will resolve the issue temporarily, there is a Microsoft hotfix KB2545850 that offers a permanent fix to the issue.

Description:
Application pool 'DefaultAppPool' is being automatically disabled due to a series of failures in the process(es) serving that application pool.
Please provide near solution for this problem. I will appreciate the suggestion
IIS comes with a feature called Rapid-Fail Protection. By default an App Pool is configured to become disabled if a worker in the pool crashes 5 times within a 5 minute span.
The thresholds of this setting are able to be modified by right clicking on the App Pool going to Advanced Settings and modifying the 'Rapid-Fail Protection' properties. However, this event indicates that there is likely a serious issue in your application that needs to be resolved.
I got tensed about this issue and finally i got solved.
Please make sure that the following option is correct in Advance Settings in Application pool.
Application Pools>Default Application Pool > Right click and select Advance Settings.
And then check whether the option "Enable 32 bit applications" has been set as "False". It should be False
I got solved by did the above change.
I Got this error when i installed URL Rewrite Module, install correct URL Rewrite Module to fix this.
To verify this error cause of URL Rewrite Module check events logs .
windows logs>> System>> Click on recent Error, In Error details
it will show "Application pool 'DefaultAppPool(or
YourApplicationpool)' is being automatically disabled due to a
series of failures in the process(es) serving that application
pool."
Windows logs>> Application>> click on recent error, In error
details it will show "The Module DLL
'C:\Windows\system32\inetsrv\rewrite.dll' failed to load. the data
is the error."
I hope this will help You.
It's a registry permission issue. This should help:
http://support.microsoft.com/kb/885654
You might also need to add read/write permissions for NT AUTHORITY\NETWORK SERVICE (or NT AUTHORITY\SYSTEM or the account used by your application pool) to c:\Windows\TEMP.

Having some issues with MSDeploy on a windows server 2008 box, the internal service is throwing a 500 error without putting anything in the server's event logs.
I'm attempting to setup automated deployments using MSBuild/TeamCity/MSDeploy, and this is basically the current halting point, has anyone come across this issue before?
Thanks, Ed
To find out why you are getting this error you should enable logging.
First, enable Failed Request Tracing for the web management service. You can see how to do this by referring to the "Optional: Set Up Tracing" section of this article:
http://learn.iis.net/page.aspx/984/configure-web-deploy/
The "frebs" can be found in:
C:\inetpub\logs\wmsvc\TracingLogFiles\W3SVC1
Open each of the frXXXXXX.xml files with IE and it'll use the freb.xsl transform to generate a nice report.
Don't delete freb.xsl when you're done, it doesn't always get recreated.
Then turn on logging for the web management service:
http://technet.microsoft.com/en-us/library/ff729437(WS.10).aspx
You want to have the following registry entry configured:
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\IIS Extensions\MSDeploy\1]
"EnabledTraceLevel"=dword:00000002
"EnabledTraceSources"=dword:000001ff
You can fiddle with the tracing levels/sources to increase and decrease the verbosity of the logs.
As per the article the management service logs are written to:
%WINDIR%\ServiceProfiles\LocalService\AppData\Local\Temp\WMSvc.log
