Try again with: http://people.redhat.com/~ikent/autofs-5.0.5-54.bz827024.1.el6/ Same version of autofs and any access to /net/nfs breaks it. The above package fixes the problem.
Core was generated by `automount --pid-file /var/run/autofs.pid'.
Program terminated with signal 11, Segmentation fault.

(In reply to comment #1) > Try again with: > http://people.redhat.com/~ikent/autofs-5.0.5-54.bz827024.1.el6/ Confirmed, these packages fix the issue for me as well. As per comment #5, QE will not ack it. bug 827024 is private, so ack this bug to show to customers. The bug is a duplicate of the private bug 827024 which has verified by QE, and this bug also verified by customer too, so change it to verify. Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA. For information on the advisory, and where to find the updated files, follow the link below. If the solution does not work for you, open a new bug report. http://rhn.redhat.com/errata/RHBA-2013-0462.html customer verified the patch and issue resolves. --- Feedback from customer ---- This fixed the problem. I can now: cd /net/non-nfs-host where non-nfs-host is some real host not running nfs and it times out instead of crashing the automount deamon: ------------------------------ |
