Ehcache -> outofmemoryerror using ehcache 4.1.2 snapshot -> Go to message
When this error happened, we were just using the tomcat default values, while the Terracotta servers had -Xmx512m and -Xms512m.
We recently increased the MaxPermSize to 256 to see if that makes any difference and we are still awaiting the results of that experiment. We are the using hibernate ehcache 4.1.2 snapshot.
Ehcache -> outofmemoryerror using ehcache 4.1.2 snapshot -> Go to message
Hello all,

I am having a problem using the hibernate-ehcache 4.1.2 snapshot. Tha caches seem to be working well at first, but then after approximately 2 days, i start top get outofmemoryerrors, which seem to be originating when i attempt to retrieve objects from a cache.

The stack trace is as follows:
Code:

apparntly from this, it is being caused by the a cache retrieval from something we call the "privateTreeCache". Its config is as follows:

Code:
<cache name="privateTreeCache" maxElementsInMemory="5000" maxElementsOnDisk="100000" eternal="false"
 		timeToLiveSeconds="3600" overflowToDisk="false" statistics="true">
 		<terracotta>
 			<nonstop>
 				<timeoutBehavior type="noop" />
 			</nonstop>
 		</terracotta>
 	</cache>

Hi there,

I was just wondering of there is an update on this issue - I seem to be having exactly the same issue using Hibernate 4.1, ehcache terracotta 2.5.1 and terracotta toolkit 4.1.
It's a shame, because it seems to be the only thing holding back a release right now.

Sorry to be a nuisance and let me know if any further detail is needed.

rich.
