Hello,
My Zimbra sometimes hangs and need to be restarted to recover service.
RAM and CPU are not 100% when problem occurs.
What I see is "concurrent mode failure" lines in /opt/zimbra/log/zmmailboxd.out like this one :
(concurrent mode failure): 943100K->943104K(943104K), 2.7525200 secs] 1226037K->1066163K(1226048K), [CMS Perm : 115675K->115675K(200204K)], 2.7530060 secs] [Times: user=3.26 sys=0.00, real=2.75 secs]
I didn't find solution for this. Can someone help me please ?

Hi,
Your zimbra version is quite old. Please upgrade to the latest version. Have a look at this alert: https://blog.zimbra.com/2019/05/9826/

Re: concurrent mode failure
I know this but for any reasons I don't want to upgrade now. And this can be worst upgrading an unstable zimbra.

Re: concurrent mode failure
Hi, it's better to migrate your zimbra to a new system, not doing in place upgrade. You can search the wiki for howto.
