This is more than likely a memory leak issue in the the JSP compiler but this can be easily resolved.
What you will have to do is set your environment variables. Within a *nix based system you will set it as such in the home.properties file or as an environment variable:
export JAVA_OPTS ="-Xms(memory size) -Xmx(memory size)m -XX:PermSize=64m -XX:MaxPermSize=128m"
I would suggest your (memory size) be 1024 mb. After doing this you should reinstall.
