When browsing to http://webserver/oneNet/NetStorage I am presented with the
following error:

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

If you think this is a server error, please contact the webmaster.
Error 500

I'm not sure where to start troubleshooting this. NetStorage was working at
one time on the server. The Admin and Normal instances of Tomcat both appear
to be running.... http://webserver/oneNet/nsadmin page comes up
successfully, and I haven't changed any of the NetStorage settings in there
for some time.

I'm running Netware 6.5 SP4, Apache 2.0.54

Any ideas? Thanks!
