Oops. Good point. So much for my detective work. So the only other thing I can see is either the GetFileAttributes or the CreateFile itself.

Re: cygwin randomly pauses under Win2k
Chris J (Not to be confused with Chris F), How about sending along the source code for your small program, so I can give it a wiz-bang. So far, running strace on my system seems to make the problem I have go away, so if you can readily reproduce the behaviour, I would like to try it on my system. Thanks.

And the only thing in set_security_attribute() which could take a lot of time is the call to LookupAccountName() which is only called if the /etc/passwd file doesn't contain the SID for the user *and* which can only take a lot of time if the machine is asking a DC.

Re: cygwin randomly pauses under Win2k
Great! I set up a strace on the 'doit script', and the very act of running strace seems to make everything behave as expected. But, I can't run this thing all the time, as strace generates a small quantity of output. Oh well, I'll keep monitoring it for a while and see what comes out.

cygwin randomly pauses under Win2k
I have this wierd behaviour, and it is causing some stats that I run to whack out. Every now and again (every 15-30 minutes or so), my cygwin apps pause for 1-2 MINUTES I have written a simple script to capture this behaviour: $ cat doit #!/usr/bin/bash while [ 1 ] do echo `date` Starting >> doit.log /usr/bin/time -o doit.log -a sleep 60 echo `date` Ending >> doit.log done I have also written a quick sed script to filter the output from time: $ cat gettimes #!/usr/bin/sed -f s/^.* \([^ ]*\)elapsed .*$/\1 elapsed/ /^0inputs.*$/d And here is some of the offending output Tue Apr 16 09:40:53 2002 Starting 1:00.13 elapsed Tue Apr 16 09:41:54 2002 Ending Tue Apr 16 09:41:54 2002 Starting 1:00.11 elapsed Tue Apr 16 09:42:55 2002 Ending Tue Apr 16 09:42:55 2002 Starting 1:00.21 elapsed Tue Apr 16 09:45:45 2002 Ending Tue Apr 16 09:45:46 2002 Starting 1:00.16 elapsed Tue Apr 16 09:46:46 2002 Ending Tue Apr 16 09:46:47 2002 Starting 1:00.16 elapsed Tue Apr 16 09:47:47 2002 Ending What's interesting is that between seconds 42 & 45, time shows an elapsed time of 1:00.21, but the system clock has actually elapsed 2 minutes & 50 seconds, (unless there is some major hangups in the invoking of the echo and/or `date` commands). I am working on this machine, so I know that there are no 2-3 minute pauses in user responsiveness Has anyone else experienced this kind of behaviour??
