Subject RE: memory leak in PoolableProxyHandler
Date Wed, 30 Jun 2010 07:05:34 GMT
I'm dissapointed to have come to the same conclusion.  It's really a huge memory leak. 

My settings for tomcat were 

JAVA_OPTS="-Xnoclassgc -Xss1536k -Xms1536m -Xmx1536m -XX:NewSize=128m -XX:MaxNewSize=128m
-XX:SurvivorRatio=2 -XX:+DisableExplicitGC -Xloggc:/home/pxprod1/logs/GC_tomcat_productinformation.log

I created a few cocoon services over the last few weeks which had to transform about 10.000
products.  After about 5000 products I ran into java.lang.OutOfMemoryError: Java heap space.
 This was quite consistent behaviour and after a day of profiling using Jrockit Management
Console and Yourkit Java Profiler my investigations led to this issue.

Why is this patch not being committed to trunk if it is such severe?  Ps.  I think I'm confident
to say I can lower the memory settings now to < 800mb after applying the patch.

Kind regards,
Robby Pelssers

Unfortunately not. The patch is even not committed to the trunk.
