Zimbra nginx process defuncting 3000 times per second

[Day]

Hi everybody,

i'm new to the forum and to zimbra, please be kind to my errors.

I've installed the debian 32 bits opensource edition of zimbra 5.0.6 on a 32 bits updated Debian etch, on a 64 bits server.
With only 5 mail users and only some 20 mails a day, my load average is strange : 2.6.
So i went to see top : it seems nginx is birthed and defuncted 3000 times a second.
I've got a 9.4GB /opt/zimbra/log/nginx.log file, with something like 10000 lines added each second.
Looking on google, the zimbra forum and bugzilla, with the errors from nginx.log, i couldn't find a similar problem (but well, as i said, i'm a newbie with zimbra).
So i wonder if you could point me to my (i hope) obvious failure :-)

Here is the version, load, top, nginx.log and zimbra config :

that's quite an impressive respawn rate. methinks nginx should do a better job of missing memcached than that..

ps -ef |grep memcache
zmcontrol status
(is proxy/memcached reporting not running).

zmproxyctl stop
zmproxyctl start
see if that helps.

Thanks for your help :-)
Nothing is better, i still got more than 13000 lines in nginx.log in less than 3 seconds.
Here are the results of your suggested commands :

$ ps -ef | grep memcache

I would hazard a guess and say your /etc/hosts file is incorrect. Look for the line beginning with:
127.0.1.1

and make sure it *doesn't* have your hostname or fqdn - it should just have localhost. your hostname/fqdn should only be on proper ip address line.

[Day]

You were right :-) Lots of thank you for you !

My load average is now below 0.2 instead of 3.
No more error in nginx.log.

For the record, i had in the ipv4 part of /etc/hosts :
127.0.0.1 localhost
127.0.1.1 emma.enc emma
192.168.10.20 emma.enc emma

And now, i have :
127.0.0.1 localhost
127.0.1.1 localhost
192.168.10.20 emma.enc emma

[Day]

By the way, could you explain me or point me to an explanation as to why i should just have localhost ?
