Error registering RequestProcessor

[John Sidney-Woollett <jo...@wardbrook.com>]

We're using Tomcat 5.0.28 which is fronted by Apache 1.3.29 + modjk 1.2.6

We're seeing this error message in the logs occasionally. The error 
occurs at any time interval AFTER tomcat has been started up - two hours 
was the last time it occured after startup.

This server is one of two in a (jk) load balanced configuration - they 
do not use or share sessions and act purely as image servers (from a db 
+ file system).

WARNING: Error registering request

Does anyone know if this is this serious? And do you think that this TC 
instance is still able to serve requests. (Because this is our 
production environment we can't do much testing with these servers and 
haven't seen the error on our development servers).

Thanks for any insight or help.
