JVM is crashing after 1hour
---------------------------

                 Key: JBFORUMS-284
                 URL: https://jira.jboss.org/jira/browse/JBFORUMS-284
             Project: JBoss Forums
          Issue Type: Bug
         Environment: Both Windows XP SP2 and Red Hat Linux 3.2.3-20
            Reporter: Ravi M

Hi,

We are facing JVM crash problem when we are running load test on my web application in JBoss.

In our application we are using ChartFX6.5 from SoftwareFX to generate graph images.
We are using Java concurency to generate 6 graphs concurrently. And CXF to expose app as webservice

When we are normally hitting application adhoc, we are not facing any problem, even its running successfully many days.

When we are doing load test as like production JVM is getting stopped by generating on error report, after generating ~5000 graphs in 1Hr,

--------------------------------------------------------
#
# An unexpected error has been detected by HotSpot Virtual Machine:
#
#  SIGSEGV (0xb) at pc=0x56eedc46, pid=16021, tid=1438505904
#
# Java VM: Java HotSpot(TM) Server VM (1.5.0_11-b03 mixed mode)
# Problematic frame:
# C  [libcmm.so+0x2cc46]
#
------------------------------------------------

Load Test Spec:
---------------------
LoadTest time: 1 Hr
Concurrent Users: 1 to 5


Specifications:
--------------------
JDK: jdk1.5.0_11
JBoss: jboss-4.0.5.GA-v1.0.22
LoadTest Tool: Eviware SoapUI

After identifying this problem we tried tracing it in the following scenarios.
 When we ran application with single user & single thread for graph generation  ----  jvm crashed after ~5000 graphs
 When we ran application with ChartFx 6.0 version ----  jvm crashed after ~5000 graphs
 When we increased the delay in each request in load test  ----  jvm crashed after ~5000 graphs
But 
 When we ran same application war file in Tomcat4.1 with JDK1.5 ---- Successfully completed 2 HR test with 10,000 graphs

Could any one assist us how to proceed further to resolve this problem.
Thanks in advance.
