Zimbra high CPU usage with java process

I've been running Zimbra 8.0.2 and got a problem with almost 100% CPU usage with java processes.
I tried many solutions by applying the fix written on the forum but didn't work.... Finally found the solution for this.


NIO imap, NIOSocketSession leaking. 
IMAP NIO is enabled by default with Zimbra 8.0.2. That's why Zimbra takes high CPU usage.

To disable IMAP NIO, excute the following command.

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