Hello,
I'm running into a problem where my GeoServer instance is requiring periodic reboots. GeoServer stops responding to requests like Layer Preview and WMS queries, but other content like the About GeoServer page work fine. After the reboot, everything works fine for several hours.
The configuration is GeoServer 2.2, Tomcat 6, Apache 2, Sun JVM 1.6, and RHEL6. The jvm flags are:
-DGEOSERVER_DATA_DIR=/data
-DGEOWEBCACHE_CACHE_DIR=/cache
-DGWC_METASTORE_DISABLED=TRUE
-DGWC_DISKQUOTA_DISABLED=TRUE
-server -Djava.awt.headless=true
-Xms2G -Xmx2G -XX:MaxPermSize=512m -XX:PermSize=128m
Has anyone else run into needing periodic reboots to fix stalling?
Thanks,
-Darren

Darren,
could you provide some more details about the status of geoserver during failures?
Essentially the logs and the stack can be a good start of point for investigation.
For stack use: jstack -F PID > trace.log
Cheers,
Carlo

Looking at the trace I can see some blocked threads and some other processing, probably you need to profile the application, anyhow let’s see if we can understand which are possible causes with some more investigation.
A first good step should be the control flow extension installation: (http://docs.geoserver.org/stable/en/user/extensions/controlflow/index.html) especially setting up the timeout and the maxRenderingTime.
Then come back with news
