Zimbra stops working properly after some hours

Post by ninjavz »

Well I have changed the approach. I had made two copies of the VM hard disks (May15 and May16). This problem appears with May16, so I did a fallback and restored the snapshot from May15. This has been working, even though /etc/hosts was wrong, which has also been fixed. So that is not the problem described in the beginning.

The only thing I changed during those hours was setting zmtlsctl to redirect and I installed EPEL repo and fail2ban.

Anyway, falling back to May15 version since sunday 17 afternoon. Server has been working perfectly.



One other thing I noticed different between both versions, is that tha Active QUEUE had an email stuck that only showed an ID and in the last column something like /NaN/NaN/0NaN which I believed was odd. Since it was not going away I deleted it. But after some seconds it reappeared.

Is it possible to hang Zimbra by sending some oddly built email message?



Sadly, I do not know what was hanging the server. The current version is running and I will be changing some additional options always making a snapshot of the VM before.

If at some point I find the problem I will report it here.



Thank you.

Update 27.May.2015

On sunday 24 May, I made just one change to the server, I activated rsyslog to report to another server /etc/rsyslog.conf:

*.* @@server.domain.com:514



The server run until Tue 29 May aprox 1:45am. Then it stopped working properly, everything slow as described before.

MTA was stopped. Hard reset on Tuesday morning. I commented that line and restarted rsyslog.



Now working properly but still testing. If it works until sunday it may have something to do with the problem. Will let you know.
