        Have you checked `netstat -na` (or equivalent) to see if you are 
running out of ports?  200 ports per second times 2 minutes (typical) TIME_WAIT 
yields 24,000 ports in churn, which tends to increase as resource usage 
increases and the OS is slower in getting around to cleaning them up.

        To test this theory, change '-t un' to '-t u1', just for test purposes.

        A possible workaround is to add multiple IP aliases to the addresses 
(make sure they're not in use!) and use the injection file to bind the call 
source to different aliases, thus slowing down the churn rate on each address.


        HTH,

Mike
