Hello,
The last month or so, I've been seeing strange errors in the event viewer. Here are the most recent ones:

2009/12/15 14:36:27 Pid: 22567, comm: smbd Not tainted 2.6.25.13-oe32 #61

2009/12/15 14:36:27 [] syscall_call+0x7/0xb

When this happens, I generally lose network access to the RAID and need to restart. I can still access shares of other RAIDs in the same system, so it's not hard locking... although it has a few times in the past with similar messages.
Any ideas what could be causing these errors (and what do they mean)?
