java.lang.OutOfMemoryError: Java heap space

Hi,

Today we've had a problem with the Aware service (running on Windows server).

First we saw a few lines like this in the logging:

INFO | jvm 1 | 2017/10/06 07:30:46 | com.bas.basserver.executionengine.ExecutionException: Operation error.
INFO | jvm 1 | 2017/10/06 07:30:46 | at com.bas.basserver.executionengine.rliproc.F.resume(Unknown Source)
INFO | jvm 1 | 2017/10/06 07:30:46 | at com.bas.basserver.executionengine.ExecutionEngine.A(Unknown Source)
INFO | jvm 1 | 2017/10/06 07:30:46 | at com.bas.basserver.executionengine.ExecutionEngine.handleServiceReplyNotification(Unknown Source)
INFO | jvm 1 | 2017/10/06 07:30:46 | at com.bas.basserver.bsmanager.F.A(Unknown Source)
INFO | jvm 1 | 2017/10/06 07:30:46 | at com.bas.basserver.bsmanager.F.A(Unknown Source)

and later on:

INFO | jvm 1 | 2017/10/06 07:31:03 | java.lang.OutOfMemoryError: Java heap space
INFO | jvm 1 | 2017/10/06 07:31:07 | Exception in thread "ActiveMQ Transport Server: tcp://localhost:61616" java.lang.OutOfMemoryError: Java heap space

and

INFO | jvm 1 | 2017/10/06 07:31:07 | Out of memory error encountered in the source QS

and then it died:

INFO | jvm 1 | 2017/10/06 07:31:19 | java.lang.OutOfMemoryError: Java heap space
INFO | jvm 1 | 2017/10/06 07:31:21 | Server daemon died!

Is this caused because the server had not enough memory?
Or is the memory allocated in the Aware configuration (512MB) not enough perhaps??

Other causes??

Try checking the memory settings for AwareIM and Tomcat under the Setting Tab in the configurator.
try 1024mg for each is they are less.
Also if you are running AwareIM as a service there is a file that has memory settings in it that you can change to increase the memory. Sorry, forget the file name may be the BasServer.props file?

Hi rbroos, thanks for your reply.

I already changed it in the Configuration tool.

Actually I thought that these setting were also applicable when you run Aware as a a service.

@Aware support: what exactly do I have to change to increase memory when running Aware as a service??

C:\AwareIM\bin\awareim.conf
FROM
wrapper.java.initmemory=20
TO:
wrapper.java.initmemory=1024

C:\AwareIM\bin\wrapper.conf
FROM:
wrapper.java.maxmemory=96
TO:
wrapper.java.maxmemory=1024

Hi Ben,

I see in awareim.conf and wrapper.conf both lines.

Do I have to change the initmemory in awareim.conf
and the maxmemory in the wrapper.conf only?

Or do I have to change both values in both files???

I don't remember from where, but I have it on my list of things to do when I update Aware version to update certain files and values.
And in this case, my notes says to do both values (Init and max) in both files. And I've never had any problems.

For development, I run Aware and Tomcat as Service than from CP, so I also set the following to give more memory for configurator:

On Development & production machine to increase configurator memory , I change to following file:
AwareIM/bin/ClientStarter.bat

%JDK_HOME%\bin\java –Xmx1024m -cp %CLASSPATH% com.bas.uiconfiguration.Application

Hi Ben,

thanks for your help !

I've changed the setting is both files and restarted the Aware and Tomcat services.

When I look at the taskmanager I see different values. The initial is set to 512mb, but the service does not consume more than 180mb until now.
Is this normal behaviour?
TIA,Rob

Rob, I really don't know how those numbers in the files correspond to the numbers in task manager.
