Control: tag -1 + confirmed moreinfo Hi Vincent,
thanks for the bug report. Vincent Lefevre wrote: > I had a screen window with a shell (zsh) and quit the shell.

See http://savannah.gnu.org/bugs/?func=detailitem&item_id=25089 Could your issue be related or even identical to the one above in the upstream bug tracker? (I currently assume so, hence the "confirmed" tag.) Unfortunately so far I wasn't able to reproduce this on demand. And for some reason, so far this issue — if seen at all — has mostly been seen when Screen runs on virtual machines. The reason for this is though unclear, at least to me. And so it is also with my case: The only host, where I run into this issue over and over again (but always never immediately after starting Screen or trying to reproduce it) was on a virtual machine running on a VMware ESX server. There are also a few proposed patches, but some got revoked again due to other issues. Unfortunately one of these revoked patches worked for my casae quite well. Haven't tried the most recent patch yet, though. I can dig up details if you wantto try that patch.

And now easy or how long does it take until zombies appear? (Feel free to remove the "moreinfo" tag when replying to these questions.) > But it may happen that zombies disappear. That's what I noticed, too, but it can take days, maybe weeks.

I though can imagine that some of the updates caused it to happen more often. Then again, I didn't notice it so far. And I do monitor most of my boxes for zombie processes.
