OutOfMemoryError with stacktrace.
Hello -
I'm currently running JMeter 2.1.1 with Sun JVM 1.6 on RHEL ES 4 Linux
on VMWare ESX server, and am struggling with out of memory errors
running JMeter.
The same tests running on a Windows XP box (Sun JVM 1.5) don't throw out
of memory errors.
Here's 'top' output of the process :
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
24733 metatest 25 0 977m 150m 6320 S 99.2 4.0 16:20.65 java
Normally I get errors with no stacktrace:
java.lang.OutOfMemoryError: Java heap space
However, upping the JVM max. heap memory to 1.5 GB, gave of memory error
with a stacktrace (see end of email). Is this significant or useful?
Kind regards,
Sonam Chauhan

Might be a garbage collection issue?
Perhaps you could enable GC tracing on the JVMs, and compare the two systems.

What about JVM 1.6 on XP?

I don't think so.
It just shows that the JVM ran out of memory trying to log a message.
This was just "the straw that broke the camel's back", The rest of the
straw was loaded previously by other parts of the test.
