Dear Expert:
Recently on the proof WNs I see the following error message:
[root@valtical09 tmp]# service proofd status
xproofd dead but subsys locked
I removed /var/lock/subsys/xproofd and restarted the service but after some time they crash again.
I removed all the following directoreis on both WNs and proof master:
- /localdisk/proofbox/
- /tmp/.xproofd.1093
The restarting the proofd daemon on all machines again, but after some time, the proofd on the WNs crashed again while it works on the proof master.
From the logs on the proof WN I see a lot messages in connection:

From the logs on the proof master I also see a lot of error message in connection:

130508 17:24:07 9386 xpd-E: XrdProofConn: XrdProofConn: severe error occurred while opening a connection to server [valtical05.cern.ch:1093]
But the network connection between these machines should be no problem, any idea where the problem is?
Cheers,Gang
