[Linux-cluster] RHEL 5.2 - ccsd. Invalid descriptor specified (-52)



hello,

we are running a two node cluster with RHEL5.2 without problems for a long time. Yesterday we noticed some messages in /var/log/messages, which we cannot fully interpret.

Is this a indication of a network-error ? (we have two Fibre Switche and use Ethernetbonding on the hosts). 

There is no error logged on the bond-device:

[root dbcn01 ~]# cat /proc/net/bonding/bond0
Ethernet Channel Bonding Driver: v3.2.4 (January 28, 2008)

Bonding Mode: load balancing (round-robin)
MII Status: up
MII Polling Interval (ms): 100
Up Delay (ms): 0
Down Delay (ms): 0

Slave Interface: eth4
MII Status: up
Link Failure Count: 0
Permanent HW addr: 00:15:17:77:bf:82

Slave Interface: eth6
MII Status: up
Link Failure Count: 0
Permanent HW addr: 00:15:17:77:c1:90

Because I go on holidays next week I would like to ask, if I (or my colleague) have to by worried about this. 
There is no error since this event and unfortunaly we have no access for check the Fibre-Ethernetswitches.

Thank you for your help

Christian
