Summary:  Core does not close file descriptors and eventually hits ulimit

Original Submission:  It would appear that core does not always close dormant 
file descriptors which causes open file descriptors to increase to the point 
that core stops working due to reaching max ulimit.  This happens on both 
Jaguar and Panther and versions 2-5-22 and 2-5-16 of mlnet (current version of 
Panther is 10.3.6).  Using lsof, the problematic file descriptors look like:

mlnet      1551 jume  113u  IPv4                   0t0      TCP no PCB, 
CANTSENDMORE, CANTRCVMORE

Hypothesize that this is due to a connection that is not closed properly at the 
other end and core does not detect that the file descriptor is no longer usable 
or needed.  After some period of time these file descriptors keep increasing 
until the ulimit is reached and core hangs.
