Hello,
In the NFS access operation,
"chown guest.guest file" causes the process hang.
[NG pattern]---------------------------------------------------------
<server kernel-2.6.9>
1. System startup
# chkconfig --list | egrep "nfs|rpcidmap"
nfs 0:off 1:off 2:on 3:on 4:on 5:on 6:off
rpcidmapd 0:off 1:off 2:off 3:on 4:on 5:on 6:off
nfslock 0:off 1:off 2:off 3:on 4:on 5:on 6:off
#
# cat /etc/exports
/work *(rw,sync,no_root_squash,fsid=0)
#
# ls -ld /work
drwxr-xr-x 3 root root 4096 Mar 16 13:22 /work
#
# grep guest /etc/passwd
guest:x:501:501::/home/guest:/bin/bash
#
# cat /etc/idmapd.conf
[General]
Verbosity = 0
Pipefs-Directory = /var/lib/nfs/rpc_pipefs
Domain = localdomain
[Mapping]
Nobody-User = nobody
Nobody-Group = nobody
[Translation]
Method = nsswitch
#
<client kernel-2.6.9>
1. System startup
# showmount -e nfsserver
Export list for nfsserver:
/work *
#
# grep guest /etc/passwd
guest:x:501:501::/home/guest:/bin/bash
#
# mount -t nfs4 nfsserver:/ /mnt/nfs
# df

# cd /mnt/nfs
# ls -l hogehoge
-rw-r--r-- 1 root root 9 Mar 16 2006 hogehoge
# chown guest.guest hogehoge
hang.
[OK pattern]-----------------------------------------------------------
<server>
1. System startup
2. /etc/init.d/rpcidmapd restart
:

It is the same as the operation of mentioning above.
This problem doesn't occur if rpcidmapd is restart.
Is it a problem of my setting?
Or, NFSv4 problem?
Best Regards,
Sagawa.

The problem appears to be an error in our code that only exhibits the
problem when used in combination with libevent-1.0b. When used with
other versions of libevent, the problem doesn't appear...
(Hopefully) attached is the patch.
