Problem with Synchronous Collaboration

Hi,

Our University has a working CMAPServer Version 5.04 installed on a VM with Windows Server 2003 SE SP2 and 1GB RAM. The server being used by several students and teachers.

It is working fine, but recently we found an issue with "Synchronous Collaboration Service" that we need to solve ASAP.

When we try to collaborate synchronously on a CMAP, an exception is thrown "CollaborationClientHandler::run: Exception while receiving messages. Disconnecting client." (See attached cmapserver.log)

Thank you very much for your help.

Best Regards,

Francisco J. Mejia

Seems like the VM is running out of memory. Try assigning more memory to it. The FAQ explains how to do it.

Hi Acanas,

Thank you for your quick response.

I checked out the maximum heap size of memory and is set to "lax.nl.java.option.java.heap.size.max=1073741824" which is the total amount of physical memory (1024 GB RAM) our Virtual Server has.

I wonder if setting it with this value would be the issue, since obviously java VM cannot use all the physical RAM.

Yes, it could be that its asking for more memory and it can't get it, but it should be able to work with Virtual Memory.
