Hi all, I have deployed a GeoServer vertical cluster in my lab (1 master, 3 slaves) and I am getting java.lang.OutOfMemoryError: PermGen space errors when I use the Web User Interface for more than 30 mins.
Some details about my setup: Hardware: 32 CPU cores, 32GB RAM, 1 TB HDD OS: Debian 7 Linux geosrv 3.2.0-4-amd64 #1 SMP Debian 3.2.65-1 x86_64 GNU/Linux Java: Oracle JDK 7 java version "1.7.0_67" Java(TM) SE Runtime Environment (build 1.7.0_67-b01) Java HotSpot(TM) 64-Bit Server VM (build 24.65-b04, mixed mode) Tomcat: apache-tomcat-7.0.56.tar.gz GeoServer version: 2.6.0 (the same issue has happened with 2.5.1) Details: I have deployed a tomcat user under /home/tomcat and I have deployed 4 separate tomcat instances. I have configured server.xml to point to different ports, and all startup without problem. The setup is behind HAProxy and I have one backend pointing to the master GeoServer so that the UI requests go only to that instance. This master instance hangs after I work a bit in the UI. The 3 slaves have no problem, even under stress by users. The initialization of the master server is done through the following shell script: export CATALINA_OPTS="-server -Xms1024M -Xmx4096M -XX:+UseParallelGC -XX:SoftRefLRUPolicyMSPerMB=36000 -XX:+CMSClassUnloadingEnabled -XX:+CMSPermGenSweepingEnabled -XX:MaxPermSize=512m" su - tomcat -c /home/tomcat/tomcat1/bin/startup.sh This is part of the tomcat1 log: http://pastebin.com/f8cMQeE4 Any ideas why the PermGen goes out of memory?
