Internal Server Error

[br...@homepoint.com]

I'm running Tomcat 3.2 using mod_jk and apache.  It appears that sometimes
when Apache forwards a request to Tomcat either TC wasnt ready for the
connection or something strange because I get an immediate "Internal Server
Error" issued by Apache.

It's so immediate I can tell that Apache isn't passing the connection over
to Tomcat or something... here is what my mod_jk.conf and
workers.properties files look like.  Any help would be appreciated...

##### mod_jk.conf #####

LoadModule jk_module libexec/mod_jk.so

JkMount /servlet/* ajp13

Which Apache you use? If you use 1.3.X, comment out all these inprocess
things, since you do not do inprocess stuff. You can do inprocess only
with Apache 2.X which is still alpha...
