Actually it is hard to say what might be the actual reason for this crash.

What I find strange however is that cl_com_connection_complete_request() does 
check for 'connection_list' being non-NULL before it is being dereferenced:


that means if cl_com_connection_complete_request() would crash, when it was called 
with connection_list == NULL.

@Hugo: Having a stack trace still would be helpful, since there are three locations where 
cl_com_connection_complete_request() is being used by commlib.

With the new SGE version, we are trying to use the same java application (using one of our submit hosts as server) and seconds after the server started, java crashed reporting the following error messages:
