Server intermittantly refuses to display jsp's
I'm running Apache 2.0, Tomcat 4.1.24 and mod-jk2 on a Redhat linux 9.0
system.
The configuration (workers2.properties and jk2.properties) is the
default minimal one listed in the documentation pages for mod_jk2.
Every once in a while (after a page hasn't been accessed in a while) I
get the message
----------------------------------------------
Server error!
The server encountered an internal error and was unable to
complete your request. Either the server is overloaded or there
was an error in a CGI script.
If you think this is a server error, please contact the
webmaster
Error 500
vorpal.mcs.drexel.edu
-----------------------------------------------------
Reloading the page solves the problem (!). The only error message in
error_log is
---------------------------------------
workerEnv.init() create slot epStat.5 failed
[Tue Apr 29 10:33:14 2003] [error] mod_jk.handler() Error connecting to
tomcat 21000
-------------------------------------------
This is a major problem because the site is used for class information
to be read by very computer-illiterate (even computer-hostile) students
who give up if the first attempt to access the page fails.
Any suggestions?

I think I've solved this problem. I declared shared memory in
workers2.properties
and the problem appears to have gone away.
If this is a fix, I think the standard minimal example configurations
should be updated to include this (with, maybe, a comment saying that
this is needed for Apache). In general, mod_jk2 is very poorly
documented so that it is hard to figure this out from the documentation.

I am making a guess only, but is there a chance that Tomcat recompiles these
jsp's when you first try to access them and that Apache simply times out
because of the compilation time? Have you tried precompilling all jsp's?
