[CentOS] Postfix - no nfs mounted shares on server - but nfs related problem in maillog.

Hi all.

I have one server with problem in maillog:

Feb  6 06:46:26 host1 postfix/qmgr[24296]: fatal: qmgr_move: update
active/4DE015AC536 time stamps: Stale NFS file handle
Feb  6 06:46:27 host1 postfix/master[4487]: warning: process
/usr/libexec/postfix/qmgr pid 24296 exit status 1
Feb  6 06:46:27 host1 postfix/master[4487]: warning:
/usr/libexec/postfix/qmgr: bad command startup -- throttling


ls -la /var/spool/postfix/active | tail -10
-rwx------   1 postfix postfix   25367 lut  5 03:28 9F38A2D89FD
-rwx------   1 postfix postfix   22198 lut  5 03:28 9F5D45AC094
-rwx------   1 postfix postfix   22219 lut  5 03:28 9F90F5AC323
?---------   ? ?       ?             ?            ? 9FBB22DAE65

So there are problems with filesystem(ext3).

df -h /var/spool/postfix/active
System plików         rozm. użyte dost. %uż. zamont. na
/dev/sda5              69G   24G   43G  36% /

mount | grep sda5
/dev/sda5 on / type ext3 (rw)

/var/spool is a local filesystem, there are no nfs shares mounted on
server. Also nfs, nfslock, autofs services are disabled.
I've run fsck on / 3 days ago, there have been errors which I repaired
(fsck -y). Now the problems like ?---------   ? ?       ?
?            ? 9FBB22DAE65 show again.

smartctl -a /dev/sda

dmesg | grep sda

Any tips?
