ZIMBRA High Cpu Because of Java

Today.. i get a lil bit messy day. because my mail server made me to came to office while in Off Day.
cus the server stop responing. and after get a lot of works to access the HTOP. i got this number. What a Shit kan !!!!.


this is what ive got from HTOP.

what a mess usage...

a lot of alternatives to solve this.

First, I started with disabling services that I really wasn’t using ( not working in this version  maybe )

zmprov ms su********.com  -zimbraServiceEnabled snmpzmprov ms su********.com -zimbraServiceEnabled logger (Server Statistics and Server Status information is not captured.)
zmprov ms su********.com -zimbraServiceEnabled stats

But it did not help much fixing the CPU problem.

Second, because i see alot of watch dogs i did this  ( not working in this version  maybe )

$ su zimbra

$ zmlocalconfig -e zmmtaconfig_interval=3600 

change the interval on your own want.

and change the crontab to be like this.

0 * * * * /opt/zimbra/libexec/zmstatuslog

or the posiblest time on your mind.

Third, and the work way in my zimbra is doing this.
based on this paper.

[root]# su - zimbra
[zimbra]$ zmlocalconfig -e nio_imap_enabled=false
[zimbra]$ zmmailboxdctl restart

by the way, my zimbra is
Release 8.5.1.GA.3056.UBUNTU12.64 UBUNTU12_64 FOSS edition.
