Apache2 + mod_jk2 on FreeBSD - default socket timeout

           Summary: Apache2 + mod_jk2 on FreeBSD - default socket timeout
           Product: Tomcat 5
           Version: 5.0.0
          Platform: PC
        OS/Version: FreeBSD
            Status: NEW
          Severity: Major
          Priority: Other
         Component: Native:JK
        AssignedTo: tomcat-dev@jakarta.apache.org
        ReportedBy: mdxyz@gmx.de


I've got a problem with mod_jk2 and Apache2 under FreeBSD 5.x. 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 80 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.
