Do you guys know why SQL query might be being executed infinitely in IntelliJ IDEA's Database console unless I hit "Terminate" button ?
I have Intellj IDEA 11 and HSQLDB. When I run simple query it keeps printing something like this in output
[2011-12-15 00:19:32] 9 row(s) affected in 2724 ms
[2011-12-15 00:19:32] 9 row(s) affected in 2724 ms
[2011-12-15 00:19:32] 9 row(s) affected in 2724 ms
[2011-12-15 00:19:32] 9 row(s) affected in 2724 ms
and after I hit "Terminate" it spits
java.lang.RuntimeException: java.rmi.ConnectException: Connection refused to host: localhost; nested exception is:

It's not super-big deal but it's little bit annoying.
Any ideas why it's happening and how to fix it ?

I have deploy API manager 4.0.0 All-in-one on 2 VMs, front the system with a load balancer.
When one node shutdown by command "sh api-manager.sh stop", another swithes success and runs well , but there are some error in console like below:

Are there anything wrong in the deployment.toml?
In APIM active-active setup, each node is publishing throttling data to itself and to the other node. When you stop the other node, it can't publish the throttling data to the other node. Hence you see connection refused errors and this is expected. No harm having these error logs. It will recover when the other node is started. If you look at the deployment.toml, can find the other node details under the throttling configurations.
With a successfully migrated Alfresco (5.2 to) 7.0 repository, I get PSQLException: SSL error: readHandshakeRecord (see stracktrace below) every morning at 4:00, which then causes the repository to stop responding.
Could someone please help me decipher this stack trace? Why is this job running around 4am? I can't find a suitable quartz job. Does anyone know how to manually force this call to fix this problem? At first I thought it might be related to the contentStoreCleaner running at 4:00 am, but disabling this job doesn't change anything.
The only work around I found so far was to disable the activity workflow engine.

The stacktrace was misleading - the jdbc connection problem was caused by memory filling up by the Alfresco trashcan cleaner module: OutOfMemoryError: Java heap space due to no limit on getChildAssocs.
We have ~ 4 million nodes in the trashcan and the module retrieves in every batch run all nodes again and again until the memory has been filled up ...
I'm using grakn core 1.8.4 with Windows 10. The grakn server and grakn storage are starting up normally, but when trying to load a schema, Grakn returns the following error message:
Unable to create connection to Grakn instance at localhost:48555
Cause: io.grpc.StatusRuntimeException
UNKNOWN: ID block allocation on partition(30)-namespace(0) timed out in 2.000 min. Please check server logs for the stack trace.
I already checked and there are no other processes listening to the same port. I also disabled the Firewall and that did not solve the problem. Does anyone have any indication of how I should proceed?
Below is part of the log:

If you get this error, you can try to increase the wait time with the following two parameters in the grakn.properties file:
# The number of milliseconds that the JanusGraph id pool manager will wait before
# giving up on allocating a new block of ids
root.ids.renew-timeout=10
# The number of milliseconds the system waits for an ID block reservation to be acknowledged by the storage backend
ids.authority.wait-time=10
I solved this by increasing the below parameters from 10 o 100 in the .\grakn\server\conf\grakn.properties configuration file.
Not sure if this affects performances.
# The number of milliseconds that the JanusGraph id pool manager will wait before
# giving up on allocating a new block of ids
root.ids.renew-timeout=100
# The number of milliseconds the system waits for an ID block reservation to be acknowledged by the storage backend
ids.authority.wait-time=100

Thanks for responses, This was a firewall issue with target machine.
Disabled the same and everything worked fine

I'm trying to run JMeter on a remote server. I'm running JMeter-server on a new VM instance, and the GUI client from my desktop.
the remote server ip is 148.6.60.8
I've edited jmeter-server file RMI_HOST_DEF=-Djava.rmi.server.hostname=148.6.60.8

Add to your client jmeter in user.properties:
host=148.6.60.8
Otherwise JMeter can't guess that it needs to connect to the remote server on this IP.
