Then i have to manually stop and start zmcontrol service .

Then all services runs fine & users can open their webmail

Further when i query mysql

[root@mail ~]# mysql
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)

My host file is

# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
192.168.1.12 mail.mydomin.com mail

[root@mail ~]# lsof | grep TCP | grep 110
java 20675 zimbra 110u IPv6 62545 TCP *:5223 (LISTEN)

[root@mail ~]# fuser -n tcp 110
110/tcp: 20675

I can't deploy any other major changing to server without confirmation . As its mine production server.

Please help me to resolve it .
thanks.

Do not add your threads to a post that is marked as Solved and have nothing to do with your question, it's rather confusing and won't necessarily get you an answer.

You've posted no information that's useful in debugging this problem. What errors do you see in the log files when this happens? Have you also searched the forums for similar problems to see if there's a solution?

You've also mentioned that you tested MySQL by using the 'mysql' command, that won't retrun any useful information as you've run it as root, Zimbra runs MySQL on it's own port.

If you're behind a firewall or NAT router then I'd also suggest you check your Split DNS (you're server is extremely slow to respond) and see if everything is OK, go to the SPlit DNS article and look at the 'Verify...' section for details of what to do.
