Description Deke Clinger 2007-02-14 13:55:49 EST
Description of problem:


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

autofs-5.0.1-0.rc2.15

How reproducible:

on demand with the automount maps & config I'm using

Steps to Reproduce:
1. start autofs with a direct map of 5000 entries or so
2. watch memory usage
3.
  
Actual results:
automount process grows to 800Mb+ resident size within a few days

Expected results:
I'd expect this process to use 10-15Mb based on previous experience

Additional info:
autofs-5.0.1-0.rc3.10 from: 

ftp://ftp.kernel.org/pub/linux/kernel/people/raven/

seems to improve on this tremendously. 

Stable & reliable automount is extremely important for us here. Thanks for
looking into this.

This is the Fedora package.
The RHEL 5 package will have a different revision.

You must be hitting the issues that were resolved in 
revision 0.rc2.24. I can't see further memory related
problems following that.

The latest revision in 5.0.0 is 0.rc2.42 and the latest
revision in the RHEL tree is 0.rc2.43.

RHEL5 tracked the the autofs package in lock step until
the final freeze. While there are several patches I will
be proposing for release 5.1.0 the memory leak fixes that
I'm aware of are all included in the current release.

I can make the current RHEL revision available in the
same way that you got autofs-5.0.1-0.rc3.10 if you would
like to check it out.

Sorry, this may be al little confusing.
Below the 5.0.0 and 5.1.0 refer to the RHEL product
not autofs which is of course version 5.0.1.

Hello,

I'd much appreciate it if you'd put the RHEL5 package up on the ftp server.

Done.

Unfortuneately, kernel.org has been heavily loaded lately
and changes seem to take a really long time to propogate
to the mirrors. It will get there in time.
