We have a Java Spring MVC web application that is deployed on Tomcat. For the last few months, we have been experiencing an exception on a regular interval (after every 11 days) due to which our application stops working & starts throwing HTTP 500 Internal Server Error for every request. We have also observed that our Servlet-to-JSP forwarding is messed up & there are quotes in the file path - File [/WEB-INF/tiles/fragment/applicationHeader.jsp]
Our system configuration is:
JVM Version: Corretto 11.0.3+7-LTSServer: Apache Tomcat 9.0.22
Following is the exception stack trace.

Was using 7.1.2 version of JBoss EAP (which has this issue), upgrading to 7.1.3 fixed the issue.
It seems you are encountering issue reported in jira This issue is encountered when JBoss API's try to read information about deployed application. This issue is fixed in latest wildfly release.
Short question. Any ideas on the following stack trace in nexus logs?
I could probably find a solution myself, if I even understand what the error was :)
ERROR [p21752992-57395] - org.sonatype.nexus.proxy.maven.maven2.M2Repository - Got RemoteStorageException in proxy repository "Maven Public Dependencies" [id=mavenpublicdependencies] while retrieving remote artifact "ResourceStoreRequest(requestPath="/org/apache/maven/surefire/surefire-junit4/2.16/surefire-junit4-2.16.pom")" from URL groups:public/, this is 1 (re)try, cause: org.sonatype.nexus.proxy.AccessDeniedException: Access denied on repository ID='public', path='/org/apache/maven/surefire/surefire-junit4/2.16/surefire-junit4-2.16.pom', action='read'!
We are trying to use Web Deploy to improve our deployment.
Everything works internally but once we try to deploy to our online environment than msdeploy hangs on files lager than 1 MB.
If we remove those files, the sync works with msdeploy.
The client tries a few times to upload the file and then gives the following error:
Warning: Retrying the sync because a socket error (10054) occurred.
Retrying operation 'Serialization' on object MSDeploy.contentPath (sourcePath).
Attempt 4 of 25.
Info: Using ID '789c2466-2bae-4b56-b67d-1a1743cdb0f6' for connections to the remote server.
On the server we see the following error:

Anyone any suggestions to fix the problem?
I have not had this issue so cannot give you a specific fix but the microsoft documentation says
Why does remote deployment fail for large files, although local deployment succeeds?
Typically when you deploy to production servers you are deploying across a firewall.
If you get end-of-stream errors on large files, check the settings on the firewall.
Unfortuately it doesnt give specifics regarding the firewall setting to check
I am trying to implement the LinkeIN API with PECL oAuth Module, I have managed to import my contacts and the scrip works well on my Development envoirnment
But on my Live Server it raises an exception when I get redirected to my website after authentication(From Linked In Website)

2. The CallBack URL is proper

I had been breaking my head with the code, server configuration, oAuth installation, php and apache version, TimeZone and what not.... but had No Luck….
Finally, I found my way and thought of posting it here as it could help someone:
Stop Apache
Hunted for the PHP OAuth Module in the PHP lib directory in my case I found this at /usr/lib/php/modules/oauth.so
Copied PHP OAuth Module from my DEV server and uploaded it on LIVE server
Restarted apache and it worked!
Thanks
