Virgo Service commands are not working [message #1199793]

Whenever I am in the Virgo Server editor in the Eclipse IDE, I can not run the vsh:service commands(either list or examine)in the Server console without getting a Java OutOfMemory error.

I have tried increasing the heap memory to the following

-XX:PermSize=1024m -Xms512sm -Xmx4096m

But I'm still getting the OutOfMemory error.

I have tried telneting to the osgi command line. List works occasionally but examine never works.

Which Virgo version do you use?

I guess you have your application running in Virgo, because I cannot reproduce the OOM using plain VST 3.6.2.

Check if the problem is reproducible with standalone Virgo (to rule out Eclipse Tooling)
Remove your application and test vsh:services again (to check if memory settings are correct)

In general the problem may be caused by low memory settings, so can you please post the parameters used to start Virgo here.

I stripped out all plans and ran plain VST. The vsh:service commands list and examine both worked.

My memory settings were as follows: -XX:PermSize=768m -Xms512sm -Xmx2048m

I added back a plan that only added CXF-dosgi functionality and I got the OOM for list and examine vsh:service commands

I increased the memory settings are as follows: -XX:PermSize=768m -Xms512sm -Xmx4096

I still got OOM for the list and examine vsh:service commands

NOTE: I'm trying to debug an application that includes 2 plans. One is the main application plan and the other is the cxf-dosgi plan.

Can you post the exact message of the OOM exception?

You can investigate the OOM via the Eclipse Memory Analyzer [1]. You'll need the heap dump generated by Virgo as input.

If you are new to MAT, you can go to the Leak Suspects one-click view [2] or if this is not enough go through the Basic Tutorial [3]

It seems that there are too many objects (heap) and the problem is not caused by the number of classes (perm) or native threads (native memory).

If you have difficulties analysing the leak, please provide the heap dump so I can have a look. Have in mind however that it may contain sensitive data like login credentials and URLs that were present in the memory.
