After 15 minutes of running, heap is unchanged at ca 1.8MB and non-heap at ca 17MB. These numbers are more or less constant for all 5 processes (used jconsole). I could probably try to run the 5 processes over a period of some hours, but I doubt these numbers are going to change.

Key: JBCACHE-31
URL: http://jira.jboss.com/jira/browse/JBCACHE-31
Project: JBoss Cache
Type: Bug
Versions: 1.2
Reporter: Bela Ban
Assignee: Bela Ban
Priority: Critical
Fix For: 1.2.1
Original Estimate: 1 week
Remaining: 1 week
I was able to reproduce the OOME using a simple java program using JBossCache.
I have attached a java program CacheMemTest.java that mimicks our
actual scenario (3 threads / process posting to the same JBossCache
into the same node every time).
I ran 5 instances of this program in different JVMs in the background.
I passed numbers 1 to 5 as the arguments to the 5 programs (for the
processNum).
After about 3 hours, the program started throwing OOMEs.. The stack
trace for each of them was :
org.jboss.util.NestedRuntimeException: - nested throwable:
(java.lang.OutOfMemoryError)
at java.lang.Thread.run(Thread.java:552)
Caused by: java.lang.OutOfMemoryError
org.jboss.util.NestedRuntimeException: - nested throwable:
(java.lang.OutOfMemoryError)
at org.jboss.cache.TreeCache.invokeMethod(TreeCache.java:3184)
at org.jboss.cache.TreeCache.put(TreeCache.java:1741)
at org.jboss.cache.TreeCache.put(TreeCache.java:1724)
at CacheMemTest$PublishThread.run(CacheMemTest.java:65)
Is this a known problem? Any idea how I can go about debugging this
problem?
