[Grinder-use] Keep-alive issue

[Randy W. <kr...@no...>]

Hello all,
I've been successful doing a set of load tests for a client.  There  
was an issue with the first connection; apparently my tests were  
keeping connections open through the entire test, which was exhausting  
the connections available from the server.  So, the server config was  
changed to disable keep-alive.  However, ever since that config change  
(and no other that I know of), my test has been outputting
Out of Memory
You might want to try the -mx flag to increase heap size

at sporadic intervals.

I've adjusted my start script to

source ./setGrinderEnv.sh
java -Xmx2048m -cp $CLASSPATH net.grinder.Grinder ${GRINDERPROPERTIES}.

but there has been no change in behavior.  Any ideas why a server  
config change would cause my script to run out of memory?
