Not expecting help, just sharing.
We're running windows 2003 server enterprise edition on a quad processor
HP proliant G3. uname -a results in
[CYGWIN_NT-5.2 c7mdcs063 1.5.19(0.150/4/2) 2006-01-20 13:28 i686 Cygwin].
Yesterday I ran a script (kicked off in a makefile) to create /etc/passwd
for a subset of users in our domain. It failed w/fork errors (see below).
After the errors showed up I simplified the script by building
and running a script like:
#!/bin/bash
mkpasswd -d -u username1
mkpasswd -d -u username2
mkpasswd -d -u username3
.
.
This script (search ahead for "r7867") had about 400 uniq usernames.
When I ran it on Monday it also failed w/fork errors on random lines.
When the problem was happening there were ~105 processes running.
"net start|wc -l" shows 66 services.
what apparently fixed the problem:
This Tuesday morning I came in, I resumed and then closed the vim
sessions, closed the ssh sessions, then opened a new ssh session,
and then ran the more complex script 100 times in a row and it never
failed. Tonight I opened the same files in vim sessions, suspended
them, and then ran the job once and it worked fine.
We're rebooting the server tonight - it's been up just over 1 week.
Should I try a later snapshot?

thanks much,
