Description Deke Clinger 2007-12-31 23:14:13 UTC 
Description of problem:

sending a HUP signal to the automount process unmounts all the idle direct mounts. 

Version-Release number of selected component (if applicable):

kernel 2.6.18-53.1.4.el5 and autofs-5.0.1-0.rc2.55

How reproducible:
every time

Steps to Reproduce:
1. start automount with a large (6500 entry) direct map & debug logging
2. send a HUP signal to the automount pid
3. watch syslog, observe falling count of direct map entries
  
Actual results:

direct mounts are removed

Expected results:

daemon rereads config files, picks up any new entries

Additional info:

I've been discussing this with Ian Kent already - he believes it's already fixed
in the version in CVS.

I've uploaded the current i386 and x86_64 CVS builds to
http://www.eu.kernel.org/pub/linux/kernel/people/raven/autofs.
If you need different archs let me know.

As always we must keep in mind that these are the current CVS
development and haven't completed the QA process so there may
be unexpected problems. But then that's what testing is about.

Your help is appreciated.

That should read www.kernel.org not www.eu.kernel.org.

I've downloaded autofs-5.0.1-0.rc2.79 and installed it on a test host. I'm still
seeing the same problem, but the debug output is a lot more verbose now. I'm
attaching the log to this bug. 

Thanks,

Thanks for the log.
Looks like I've been able to duplicate the problem.
I'll dig a bit deeper.

*Sigh*, the included map stuff is a bit tricky.

I'm going to mark this bug as a duplicate of bug 336961 because
the symptoms are the same and it looks like a case that was
missed in the correction for that bug.
