If you think you have a new bug, then open a case, certainly. If the netscaler crashes, there should be some indications of the failure once you drop to the shell, in:
/var/log/messages
kernel dumps in:
/var/crash

Of course, most of the reasons will not mean much except to Netscaler support.
e.g.
/flash/ns-8.0-55.3: kernel trap 28 with interrupts disabled at eip=305f6810
ns /flash/ns-8.0-55.3: Fatal trap 28: machine check trap while in kernel mode

So the best recourse is usually to open a case, or just upgrade to most recent GD release (as that is usually Netscaler support’s recommendation.)
If you think you have a new bug, then open a case, certainly.

I am using three independent clusters of 9000 NS. Thanks, Ron Ikonomou When the primary fails & it is not reachable, what type of commands are available after a reboot to check what went wrong other than it went down?
I am using three independent clusters of 9000 NS.
Thanks,

Highly appreciated! Straight forward commands... Thank you very much for the logmonitor & the rest of the Netscaler support provided here.

I am mostly interested in axploiting all dashboared & logging / debugging features of Netscaler 8.0 - still have a couple of 6.1 Please send me any Netscaler chat groups available.
