CLOSE_WAIT processes and instances HANG

Hi All,
I Know I need to update some of this but it had been running fine for quite a while.


	WebObjects 5.3.3
	OS X 10.4.11
	Java  1.5.0_13-b05-241
	WONDER 3 from a March-03-2007 Daily build
	Frontbase  4.2.7

"All of a sudden" The application is hanging often. No good idea why. Running ~10 instances of the the same code base with different launch params to connect to different client DB's

Many of the instances for will hang. The DB seems fine and we don't see all the instances for any DB fail at once. If no one hits the app they seem to stay fine such as over the weekend. Otherwise they seem to die at least once a day. The more heavily used die more often but the very lightly used die also.

I did a netstat and found many CLOSE_WAIT when the instances were hung but don't know if that is relevant.

We did deploy new features recently but no "major"  type changes.

Ideas? Suggestions?
