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.

phoenix, the link is broken -> http://community.zimbra.com/utility/error-notfound.aspx

Any did some changes to DNS and hosts, but when restarting I get this for $zmcontrol status:

Host mail.clinicasantaisabel.com

amavis Running

antispam Running

antivirus Running

dnscache Running

zimbra webapp Running

stats stopped?

after $zmcontrol start all are running... but still strange, although I had to do force the shutdown (hard reset)

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...

ninjavz · Post by **ninjavz** » Sun May 17, 2015 5:00 pm

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?

Best regards
