I've recently upgraded to W2K. Wanting to use inet-utils I ran
iu-config, and was somewhat shocked to get the blue screen of death.
I investigated this further. The BSOD occurred if I touch a file in
/etc:
$ touch /etc/abc
or
$ > /etc/abc
Touching files outside of /etc doesn't cause the problem, nor does
creating files there with explorer.
The following are examples from the corresponding event logs:
The computer has rebooted from a bugcheck. The bugcheck was:

Following hints from
http://sources.redhat.com/ml/cygwin/2001-11.t/msg00167.html
this looks to be a generalisation of the setup BSOD, (setup also
writes to /etc), which I have also experienced several times.
I disabled McAfee, but the BSOD still occurred. I half suspect that
McAfee leaves some horrible hook lying around that causes this.
After about 5 or 6 reboots, I stripped all the processes down to the
minimum, ran the touch from the vanilla cygwin "DOS" window, and I
couldn't repeat the problem. Turned McAfee on again, and fully enabled
it, and I can create still create files in /etc/. I'm about to reboot
and try again....
... and BSOD has returned.
Much playing later and I'm not that much wiser. AFAICT, the following
are required to cause the problem:
1. rxvt started from my desktop shortcut. The shortcut does
E:\home\philipa\bin\run.exe /bin/perl /work/src/scripts/misc/random-rxvt.pl -e bash
But you don't need to run the touch from this shell.
2. McAfee process running, but not necessarily enabled. (I'm not
completely sure on this one).
Note, rxvt has to be started from the shortcut to cause the BSOD. Now,
my random-rxvt.pl script (listed below - it just creates a randomly
coloured terminal) has the following comment which I wrote over 5
minutes ago so can't remember anything about it. It seems pretty
interesting:
# Invoking rxvt creates a parent "sh" (replacing the perl process) and
# a child "rxvt". When the script is launched from the command line,
# this exec works as expected. For unknown reasons, when the script is
# launched from a desktop shortcut, this exec causes a perl processes
# to appear in the windows task manager. It doesn't appear in the
# output of ps -W for instance. Seems harmless...
I feel frustrtated and clueless. Does anyone have any ideas?
