Jared,
We are AIX 5.1 and QDX 5.3 rev3 on a newer box with lots of power and still have the same issue.
Look at the hcimonitord.log.old and hcimonitord.err.old files in the $HCISITEDIR/exec/hcimonitord directory. You may see some helpful info in those logs. For us, we are getting signal 4 panics and are still trying to resolve the problem.
We are under the guidelines for processes and threads on a site so that is not an issue.
Support has recommended we make some changes to the etc/security/limits file as described in the install guide. They also recommended I place the monitor process in debug. I haven’t done that yet, but I’ve made the changes to the limits file and I’m waiting to see if another panic occurs.
Other threads on this topic have focused on the alerts processing and the path defined in the action, but I don’t think that is an issue with us.
If I find what solves this I will post it..
Regards,
