A common reason for a mod_perl server to be thrashing is
that the MaxClients was not set low enough, and your server
got real busy for some reason. Always test your server
running at MaxClients for a while to make sure that it
can handle the setting.
One way to simulate is with using ab, and setting it to
a high concurrency level, and run that for a while on your
nastiest of scripts. If this is an Apache::ASP script
that uses sessions, this will also give the session
manager a good workout, since ab will create one new session
for each request, because it does not remember cookies.
