I all,

when I start apache I receive the following error:

# /etc/init.d/apache2 restart
[Tue May 26 09:06:32 2015] [warn] worker ajp://xxx.xxx.xx:8009/sac already used by another worker
[Tue May 26 09:06:32 2015] [warn] worker ajp://xxxx.xxx.xx:8009/sac already used by another worker
Syntax OK
Shutting down httpd2 (waiting for all children to terminate) done
Starting httpd2 (prefork) [Tue May 26 09:06:32 2015] [warn] worker ajp://xxxx.xxx.xx:8009/sac already used by another worker
[Tue May 26 09:06:32 2015] [warn] worker ajp://xxxx.xxx.xx:8009/sac already used by another worker

If in the file:
/etc/opt/scalix-tomcat/connector/ajp/app-xxxx.sacapi.conf

I comment the line:
# ProxyPass /sacapi ajp://xxxx.xxx.xx:8009/sacapi timeout=30 retry=1 ttl=5 ping=5

... the error disappears.

Any help to correctly solve the problem is appreciated.

Regards.

Not sure what version of Scalix or what operating system you are using. This would certainly make it easer to assist you. I've seen similar issues with both Scalix 12.5.0 and 12.1.0 running on CentOS 6 64 bit. I tried in another thread to get some assistance but no one really was able to give many useful suggestions. Your post has give me an idea where to look.

The httpd error_log has lots of these messages, one after another:

[Sun Jul 05 21:49:36 2015] [error] ajp_read_header: ajp_ilink_receive failed
[Sun Jul 05 21:49:36 2015] [error] (70007)The timeout specified has expired: proxy: read response failed from (null) ((xxx)-mail.(xxx).net)
[Sun Jul 05 21:50:29 2015] [error] (70007)The timeout specified has expired: ajp_ilink_receive() can't receive header

I will try what you did and see if it makes a difference.

What is the result if you restart scalix-tomcat?

/etc/init.d/scalix-tomcat restart

Also what is the result from

ps auwwx|grep java

Kev.

The restart appears clean:

[root@mail ~]# /etc/init.d/scalix-tomcat restart

The "ps auwwx|grep java" gives:

Hello Mr. Miche,
