Hi,
I run a non cygwin apache process named httpd.exe. Checking it with
"ps -W" shows a listing of the same process (with PID 4560 in this
case) twice.
$ ps -W | grep httpd
4560 1604 4560 5304 pty0 1000 09:55:21
/home/georgeflorendo/wamp/bin/apache/Apache2.4.4/bin/httpd
4560 1604 4560 5304 pty0 1000 09:55:21
/home/georgeflorendo/wamp/bin/apache/Apache2.4.4/bin/httpd
7508 0 0 7508 ? 0 15:09:50
C:\cygwin\home\georgeflorendo\wamp\bin\apache\Apache2.4.4\bin\httpd.exe
Doing a "ps aux" shows it only once.
$ ps aux
PID PPID PGID WINPID TTY UID STIME COMMAND
1340 7856 1340 5720 pty5 1000 15:13:50 /usr/bin/ps
1604 4008 1604 2292 pty0 1000 09:17:01 /usr/bin/bash
4008 1 4008 4008 ? 1000 09:17:00 /usr/bin/mintty
4560 1604 4560 5304 pty0 1000 09:55:21
/home/georgeflorendo/wamp/bin/apache/Apache2.4.4/bin/httpd
<snipped>
Is it correct that ps -W shows the same process twice?
Thanks!
George

Not exactly but it could happen. Can you try the latest snapshot Cygwin DLL from http://cygwin.com/snapshots/ and see if it fixes the problem?

I don't see anything in the ChangeLog which would affect this and I'd be concerned if there was. There are scenarios where two different windows pids can be associated with the same Cygwin pid. You should only see it when you do a "ps -W". So, AFAICT, the correct answer to the "Is it correct" is "Yes'. cgf -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple ^ permalink raw reply [flat|nested] 11+ messages in thread

Didn't get to read your first sentence earlier. I'd rather have a faster cygwin more than a more accurate "ps -W". Thanks for all your help. -- George M.

Checked the latest snaphshot. ps -W still shows the same process (with same PID) twice, while ps aux shows it only once.

Here, please look at process 5952: I've put up another snapshot which causes the same cygwin pid to be listed twice with two different WINPIDs which can happen when a cygwin process is started by a windows process and then execs another process.

Thanks a lot cgf! Whew, I'm glad my reply came before 1.5 months. I'm happy to announce that the problem had been SOLVED and that the current snapshot has solved the problem. Hence, the PIDs from 'ps -W' are no longer displayed more than once. Each unique PID is displayed only once! Thank you so much cgf. All the best and more power to cygwin, George -- George M.

Can you try the latest snapshot Cygwin > DLL from http://cygwin.com/snapshots/ and see if it fixes the problem? Thanks Corinna, I've tried the latest snapshot but the results still remain the same. FWIW, here's cygcheck's output showing I used the latest snapshot. Attached too is the raw ps output. Maybe the full listing of ps and the output positions of PID 4712 could give you clues. But in any case, I've read cgf's reply and we don't want cygwin slower. I can live with listings containing duplicate PIDs :) Thank you! George -- George M.
