While trying to run captures on 2 seperate XP SP2 PC's, I have this issue:  in
a DOS screen (box) - 
16:07:05          Err  file emem.c: line 291: assertion failed: (npc->buf !=
NULL)

Press any key to exit

Then in a windows dialog box - 
C++ runtime error
this application has requested the Runtime to terminate it in an unusual way.
Please contact the app support team.

This happens everytime I start a new capture.  Anywhere from 5 to 20 minutes
into the capture.  We have a high priority app that is experiencing slowness,
so we are attempting to run captures with these parameters:  100 meg file size,
overwrite after 100 files, filtering out ports 22, 3389, 5800, 5900, 4044, and
4045.  We want these caps to run for a while so that we can go back to them
when the report of trouble comes along - instead of scrambling to get something
running when the report comes in.  While not really relevant to solving the
issue, just background as to why we have the cap's set up that way.

These are freshly built(installed) PC's (all 3 by me), only XP SP2 and all
current critical updates and wireshark have been installed.  The drives were
formatted and repartitoned before installing the OS.  They have 2 NIC's - one
for us to RDP into and the other is the monitor port for a Cisco SPAN session. 
There are actually 3 PC's for this purpose - the 3rd is working fine.

I can provide (or at least do my best) any other info you need - I just don't
know what to send right now.
