I just tried and found that I am also able to replicate the immediate crash when I log on to my session, then log off, and then back on again. Also my harddrive fills up very quickly with swap space data, this returns to normal once I exit out of the CYGWIN dos box.

I've been having the same problem with various releases of
cygwin/XFree86 for at least 6 months. This happens with both Windows 98
and Windows 98SE. I've not tried it with other versions of Windows. I
notice that when the mouse starts to become erratic the system rapidly
runs out of memory/swap resources as if there is a large memory leak.
I've also observed that this situation occurs immediately (rather than
after 15-30 min) when you logoff the host and login again without
restarting Xwin. I think cygwin/XFree86 is a great product, but this
problem very much limits its usefullness as XDMCP client.
