Apache2 + mod_jk2 on FreeBSD - default socket timeout (bug?)

[Michael Diener <mi...@synchronica.com>]

Hi there,

I've got a problem with mod_jk2 and Apache2 under FreeBSD 5.x and I think it
is a bug. I configured mod_jk2 for two Tomcat 5.0 servers. If one of these
machines is down (unplugging the network cable), mod_jk2 should send all
requests to the server that kept running. That is working 90 percent of the
time, but sometimes forwarding the request takes about 75 seconds. I found
out that this is the default socket timeout of FreeBSD. The problem is that
I configured mod-jk2 the way, that it has its own timeout for connecting
(see attached workers2.properties). But this value is not recognized. If I
decrease the default connect timeout for FreeBSD (by /etc/sysctl.conf),
mod_jk2 will use this value and everything is fine. But I don't want to
decrease that value, it could cause other problems.
So I think it is a bug, that mod_jk2 is not using the timeout values from
its workers2.properties in FreeBSD.
Btw exactly the same setup for Apache2 and mod_jk2 works fine on Linux.

Regards,
Michael
