running zcs-5.0.13_GA_2791.UBUNTU8.20090206174622.tgz and two terminal servers that are the clients web pages.

One terminal server is ok, the other one, the java client causes high cpu.
all the clients that connect share the cpu to add it up to 100%.

I'll update to ga18.. is there any thoughts what else I can do before this and the associated outage?
