Hi List,
I've been getting a lot of OutOfMemoryError errors in my logs over the past
few days, to the extent that all three instances of my live service died
yesterday afternoon!
GeoServer 2.4.3
Windows Server 2008 R2 -64bit. - The machine has ~30GB RAM, but each
tomcat instance never uses more than 1.5GB.
Tomcat 6
Environmental variables for each instance:
> set JAVA_OPTS= -Xmx5G -Xms2G -XX:MaxPermSize=256m
> set JAVA_OPTS=%JAVA_OPTS% -XX:+UseConcMarkSweepGC -XX:+UseParNewGC
> -XX:ParallelGCThreads=4
Example of the error:
2014-01-29 12:12:34,082 ERROR [geotools.rendering] - Java heap space

This hasn't happened before. The only change I've made to the systems
recently was:
- Increase all Oracle stores "Fetch size" from 1000 to 10,000
- Increase all Oracle stores "min connections" from 5 to 20.
There are two Oracle stores.
A complete set of logs is here -

Anyone have any ideas why?
Cheers,
Jonathan
