I have SIPp running on Win XP.  I am attempting to setup 128
simultaneous connections, but I only can get 8 running at a time before
I receive the error:  Warning: open file limit>FD_SETSIZE; limiting max.
# of open files to fD_SETSIZE = 64.  Currently I am trying to run just
24, but I can only get 8 simultaneous calls.  If anyone knows a better
way of doing this, let me know.  I use an audio file, usually, but I
removed it to see if that would help with the issue.  Below is a sample
of the xml file and my batch file:
 
(sample xml for one connection--4501)
