Zimbra stops working properly after some hours

Postby ninjavz » Sat May 16, 2015 7:15 pm

/etc/hosts

127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4

::1 localhost localhost.localdomain localhost6 localhost6.localdomain6

192.168.0.5 mail.clinicasantaisabel.com



/etc/resolv.conf

nameserver 127.0.0.1

# Generated by NetworkManager

search clinicasantaisabel.com

nameserver 192.168.0.1

nameserver 192.168.0.6

#nameserver 8.8.8.8



Note: I took out 8.8.8.8 because dnscache may use it and then resolves to a public IP instead of internal and then the SMTP server rejects email

The entry for your server in the hosts file is incorrect, take a look at the details in the Split DNS wiki article for the correct format.

Link -> "Unfortunately, the page you've requested no longer exists. "


Still can this hang the whole server? Looking for articles on split dns...


Now trying to connect through the webclient:


HTTP ERROR 504


Problem accessing ZCS upstream server. Reason: Cannot connect to the ZCS upstream server. Connection timeout.
Possible reasons:



  • upstream server is blocked by a firewall

  • upstream server is failing to send back the response in time

  • upstream server is down


Please contact your ZCS administrator to fix the problem.

I get 2 more servers here, kingu and marduk, I believe this is because they are windows AD controllers running DNS Server (main and backup). I erase those .1 and .6 but they come back so this must be a windows issue.



So now this is the /etc/hosts file:

127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4

::1 localhost localhost.localdomain localhost6 localhost6.localdomain6

192.168.0.5 mail.clinicasantaisabel.com mail clinicasantaisabel.com



Pings to mail, mail.clinicasantaisabel.com and clinicasantaisabel.com all resolve to 192.168.0.5, which I assume is correct.



Server is again under test to see if it hangs again...

zimbra service hanging again, everything running extremely slow, even the su - zimbra and exit.

Well this is about it, 2 weeks trying to fix this server and stil hanging... the server worked for 4 years, now this new one (as the old) keeps getting into this odd problem.


Zimbra admin kind of works, but when you try to open a user (email@domain.com) it just hangs there.

But I cannot spot exactly what service at what time goes wrong...

Hi,

This line on the hosts file is wrong -- 192.168.0.5 mail.clinicasantaisabel.com mail clinicasantaisabel.com



Needs to be -- 192.168.0.5 mail.clinicasantaisabel.com mail



Can you please change it, restart, and let us know?
