The data I posted was collected as Tomcat was restarted and for the next
19 hours.
You see too much GC thrashing, are you saying the GC process finds too
much G to clean up? Should I urge the developers to do some GC of their own?
I give 2G to start with because it may not actually /need /5g,

The system does very little swapping, both when it's GC'ing and when
it's not. Less than 100MB worth of swap is taken.
Giving Tomcat its own HW is not an option at this time, especially as
there's no guarantee it'll solve the problem. Besides it would be a VM
anyway, not physical dedicated HW.
I would start with moving this tomcat to its own hw.
Did you check swap? This long pauses could be because part of your heap is
swapped to hdd

Is there running something else in that server? Real time should be never
bigger than user+sys

Hello guys,
We are having problems on a production system with very long "full GC"
times, as long as1200sec real time (!!!).
We are using Java 6 (stuck with CentOS 5.8 at this time) and Tomcat 7.0.64.
Xmx is 5G, Xms is 2G, and GC options are -XX:+UseConcMarkSweepGC
-XX:+CMSIncrementalMode
