[Bug 282825] Re: winbindd stops and takes up 60%-100% CPU

2010-09-14 Thread Tony Wood 
Possible fix:
Greetings:  We have been getting CPU 40-50% for months on winbind. I have 
finally got of my backside as had a go at looking for a fix.  I have just done 
the following commands and the CPU dropped to 1%  It basically re-joins the 
Domain, even though we already have a Server account in the AD

sudo kinit administra...@your-ad-domain-name.net
net ads join -U Administrator

Good luck
Tony

[Bug 282825] Re: winbindd stops and takes up 60%-100% CPU

2010-03-15 Thread Aaron C. de Bruyn 
I am still running into the issue.  I just upgraded the machine this
morning from 8.10 to 9.04.  In a few weeks it will be brought up to
9.10.

The issue is most noticable with apache because the machine serves our
corporate intranet.  Whenever people try to access pages it takes 3-5
seconds for the page to return, and the entire time the likewise-
winbindd process is using up significant CPU time.

Also, I can provide developers SSH access to the box if needed for
debugging.

[Bug 282825] Re: winbindd stops and takes up 60%-100% CPU

2009-02-25 Thread Aaron C. de Bruyn 
This issue is happening to me using the copy of winbind that comes with the 
likewise-open package.
r...@crosstalk:/etc/samba# apt-cache policy likewise-open
likewise-open:
  Installed: 4.0.5-0ubuntu3.1
  Candidate: 4.0.5-0ubuntu3.1
  Version table:
 *** 4.0.5-0ubuntu3.1 0
500 http://us.archive.ubuntu.com hardy-updates/main Packages
100 /var/lib/dpkg/status
 4.0.5-0ubuntu3 0
500 http://us.archive.ubuntu.com hardy/main Packages

This is on an intranet webserver, so it's mostly used to authenticate people 
hitting apache against MS Active Directory.
I usually see two winbind processes maxing out the CPU between them.

If I attach to either process using strace while this is going on, I get the 
following:

This repeats until the process drops back to normal CPU usage.

2008-10-21 Thread Jelmer Jaarsma 
I was having this problem as well, is your winbindd also segfaulting? It
seems much related to the segfaults I reported over here:
https://bugs.launchpad.net/ubuntu/+source/samba/+bug/282733

My "workaround" was issueing a "getent passwd", that seemed to wake
winbindd up and make it work again

2008-10-13 Thread Brandon Perry 
I would also like to add that because of winbindd locking up, I cannot
use su(do) and therefore cannot kill or restart the winbindd daemon (my
tty's don't work, so I can't go through a tty). I have to restart my
computer in order to get everything working again, which lasts maybe
10-15 minutes until it locks up again.
