It's a JVM issue,.. ( your tomcat ) ...

it seems to be getting tooo much load,.. so it can't handle the requests
anymore,..

this results in a "no more threads available" within tomcat..

effectively rendering new requests useless,..
on the front end apache is still getting requests but can't pass em on
to hte back-end anymore..

Look into tweaking your tomcat and in the meantime set the timeouts
within apache to a lower number, so apache won't hang as fast once
tomcat hangs...

Hope this s

P.S. we had pretty ,much the same prob at work with a 3rd party site
written in java,.. sonce no more budget for a good code review,,.. from
our internal client, we've temp resolved the issue by having tomcat
restart everynight ( cron job in cron.daily runs at 4 AM so noone has a
prob with it since it's a site for schools,,.. last time I checked
schoolkids aren't in around that time lol )
