After a reboot, I found my users unable to log in to their email and getting this message in their browser:
It would appear that the mailbox service is not coming up ...
A network service error has occurred (zclient/io).
$ zmcontrol status
a "zmmailboxdctl start" shows this ...
zmmailboxdctl is not running.
I'm not sure if the heap space problem caused the problem or was a side effect of the problem.

$ prtconf -v | grep Memory

Thanks for any suggestions,
