one of our MARS boxes - 4.3.1 - slowed to a crawl today - to the point where no more access via GUI was possible - attempts to log in via brower took forever - tried to access "rules" page and got "system error" message on the screen.
logged in via CLI (no problem)
ran "pnlog show gui" - last line indicated no more memory available
ran sysstatus command - it showed one instance of the pnadmin (user) and java (command) using @ 99% of CPU resources (not sure if this is related to problem here but interesting)
a reboot got it going again
can't find anything in the list of current bugs for gui memory issues - anyone shed some light please?
