Looks like you have two separate problems.  The first is that your Tomcat-configured threads
get stuck somewhere, so Tomcat keeps creating more until it hits the specified limit.  Looking
at a thread dump should show you where they are stuck so you can fix your webapp (or database)
and correct that issue.

The second problem is that the JVM blew up, possibly due to your webapp creating even more
threads outside of the control of Tomcat, or perhaps eating up some other resource that provokes
an out of memory condition.  Again, a thread dump before the JVM dies should give you an idea
of what's going on.  All indications are that you have a poorly implemented webapp that's
not managing resources properly.

Also, you should always provide the exact Tomcat version you're using, and the platform you're
running on.  The only version information you provided (and that by accident) is the JVM level.
