I have a very important problem, my Zimbra server is on production (working about 800 accounts) and crashes up constantly. My log file have not any line indicating corruptions.
Suddenly my server blocks up and nothing more it can do, keyboard is dead, only mouse can moves (if I'm in X graphic mode, but any menu can not open).
My technical data are:
OS: Debian 4.0 r5 32 bits edition
ZE: 5.0.20_GA_3127.DEBIAN4.0 FOSS Edition
HD: +-500GB Raid 5
HW: HP Proliant (I don't remember model)
Pr: Intel Zeon (duo kernel)
Installation used was default, without changes, only port web server 82 instead of 80.
Give me orientation or a guide where I can find some solution, I don't have any idea what can it be (or maybe some java paremeters in web servers, I don't know [I'm not expert]).
I believed my server (hardware) was wrong, I make an identical installation in another server (same fisical features) and a backup-restore following steps in the wiki from this site, but the problem continues still.
Before, when not many users were connected server was so fast and so stable. Problem begins one month ago. Help me please. Users complain every(all) days, and only solution found at date is reboot the machine.
Thanks and regards.
