Watchdog courier-IMAP not running after latest update

Anyone experiencing watchdog insisting courier IMAP is not running?

Centos 6 x86_64

It definitely is so what can I do? I restarted courier IMAP it's unchanged.

Thanks!
 
Try to find something useful in /usr/local/psa/var/modules/watchdog/log/monit.log
Also look at Courier-IMAP section of /usr/local/psa/etc/modules/watchdog/monitrc file. Maybe it will help to find a reason.
 
Hi IgorG

I found this in the log..

But it is running, my iPad and iPhone connect to the server.

Also;


[root@server init.d]# /etc/init.d/courier-imap status
couriertcpd (pid 23697 23688 23680 23670) is running...

Can you connect to port 143 from localhost when Courier-IMAP is started?
 
How can I check this from shell? I could use another machine on the LAN via shell to check. Certainly iPhone, iPad and Thunderbird are working, both on ipv4 and ipv6.
 
We're experiencing this problem in Ubuntu 10.04, too.

POP3 and IMAP ports are open, and server is responding, but watchdog shows service Courier-IMAP stopped.
 
Hi IgorG

Nope it's working fine, definitely a bug:


[root@server ~]# telnet localhost 143
Trying 127.0.0.1...
Connected to localhost.

Watchdog should say courier IMAP is normal

Happened after a MU update, now watchdog is broken as far as detecting courier IMAP
 
Well. I will try to show and teach everyone, including experts, how report template should be filled correctly. I hope, further all will do so if they wants to receive fast and effective help from Parallels staff.

Now I will forward my report to developers for investigation and will keep this thread updated with results.
Thank you.
 
I have the same problem since one of the last microupdates. But I could not resolve it with the replacement of the monit file.

Debian 5 x64
 
Hi IgorG

Replacement of monit on Centos 6 x86_64 100% fixed.

King555 - I suggest you disable watchdog in the panel, then re-enable it as the old binary is still running in memory until its restarted. As soon as I did that my courier IMAP is green!

Let me know if that fixes it for you.
