HI!

I don't have perl installed in production servers, but it is windows server

OK, then it is windows error 10054 = Connection reset by peer.

About mod_jk configuration (mod_jk/1.2.18) :

1.2.18 does not have DisableReuse. It was first implemented in 1.2.19. Bad luck. If you upgrade (you should), then go directly to 1.2.26.

On tomcat side   <Connector port="*8009*" enableLookups="*false*"redirectPort
="*8443*" protocol="*AJP/1.3*" />

Thanks a lot

You should start with reading the (relatively) new docs page about timeouts:

http://tomcat.apache.org/connectors-doc/generic_howto/timeouts.html

They will help detect such a problem and recover more gracefully. Especially cping/cpong are helpful in early problem detection.

The pool timeouts should be helpful for closing idle connections, before you get a connection drop. Try to understand the page, and if things are unclear, ask us.

How do you know, that the firewall is the root cause?

To get a better understanding for the situation, you could compare "netstat -an" on the apache httpd side with one on the tomcat side. Look only for the relevant ports (8007 resp. 8009) and look for differences between the output. There could be small differences for a short period of time, but there should be no connections missing or being in a different state between the two outputs for a longer time (except for TIME_WAIT).

FWIW, errno 54 on my Linux 2.6/glibc 2.6.1 is:

"Error 54: Exchange full"

??!
