Subject mod_jk2 and shm
Date Thu, 05 Jun 2003 22:25:15 GMT
I keep getting errors like the following from my mod_jk2 installation.  Everything seems to
work fine but my apache_error log has errors relating to the shm worker which I don't even
configure in workers.properties since I don't see that it's in any way required for a simple
channel.socket configuration.  My load balancing through Apache seems to work fine too so
I'm pretty confused.  I've inlined the errors followed by OS and Apache information followed
by my workers2.properties.  I'm using Tomcat 4.1.24.

Should I be configuring Apache to use an on-disk scoreboard file and should I be configuring
the shm worker to point to that file?  I've tried this and the "shm.init(): No file" error
goes away but that's it.

Thanks ahead of time for the help!

Jamey
