reboot after panic hp-ux 11o

One of our servers keeps crashing.
Here is the following message that we get:

11:01 Thu Aug 31 2006. Reboot after panic: fcpbh_scsi_comp: Inbound data overf
low
12:28 Wed Sep 6, 2006. Reboot:
16:12 Wed Sep 06 2006. Reboot after panic: , isr.ior = 0'10240070.0'dcf72938

Does anyone know what would be causing this?

Thanks,
Calvin

Do you have any fiber channel device? If yes, it could have something to do with that. Check out the latest driver patches from HP.
