Description Terje Røsten 2006-12-28 19:53:43 UTC 
It might take days to trigger this problem, but it's still very painful.

The problem is that some mount just stops working, the dir in question here is
/cluster/bin:

Dec 28 16:24:10 gudrun automount[3043]: attempting to mount entry
/home/gudrun/bjornskj
Dec 28 16:24:10 gudrun automount[3043]: mount(nfs): mounted
anne:/export/home/bjornskj on /home/gudrun/bjornskj
Dec 28 16:24:10 gudrun automount[3043]: mounted /home/gudrun/bjornskj
Dec 28 16:24:28 gudrun automount[3043]: attempting to mount entry /cluster/bin
Dec 28 16:24:28 gudrun automount[3043]: mount(nfs): nfs: mount failure
susanne:/export-c/cluster/bin on /cluster/bin

Dec 28 16:24:28 gudrun automount[3043]: attempting to mount entry /home/post/mail
Dec 28 16:24:28 gudrun automount[3043]: mount(nfs): mounted

Dec 28 16:24:28 gudrun automount[3043]: attempting to mount entry /cluster/bin

Dec 28 16:24:28 gudrun automount[3043]: attempting to mount entry /cluster/bin
Dec 28 16:24:28 gudrun automount[3043]: failed to mount /cluster/bin
Dec 28 16:24:38 gudrun automount[3043]: attempting to mount entry /cluster/bin
Dec 28 16:24:38 gudrun automount[3043]: failed to mount /cluster/bin

The mount failes, while it was successful 20 min before (and there is no changes
on server or client): 

$ grep 'mounted /cluster/bin' messages| grep 'Dec 28'
Dec 28 00:04:55 gudrun automount[3043]: mounted /cluster/bin
Dec 28 02:37:39 gudrun automount[3043]: mounted /cluster/bin
Dec 28 02:58:29 gudrun automount[3043]: mounted /cluster/bin
Dec 28 03:43:49 gudrun automount[3043]: mounted /cluster/bin
Dec 28 14:44:57 gudrun automount[3043]: mounted /cluster/bin
Dec 28 15:29:53 gudrun automount[3043]: mounted /cluster/bin
Dec 28 15:50:47 gudrun automount[3043]: mounted /cluster/bin
Dec 28 16:02:57 gudrun automount[3043]: mounted /cluster/bin

At the same time I get a core dump from mount.nfs:

$ file core.29721
core.29721: ELF 32-bit LSB core file Intel 80386, version 1 (SYSV), SVR4-style,
from 'mount.nfs'
$ ls -l core.29721
-rw------- 1 root root 110592 des 28 16:24 core.29721

The core dump, /etc/auto* files and automount log attached.

BTW: the servers anne and susanne is the same host with two different
interfaces, it's running RHEL4 U4 x86_64.

What version of nfs-utils?

OK I'll try to get the right versions of everything to check
out the core dump. It could be a little hard to get this right
but we'll see.
