Description David Giddy 2006-10-30 01:13:01 UTC
Hi,

I've had a problem with smbd crashing when trying to access a CIFS file share on the local machine (127.0.0.1). I have 3 shares mounted - 2 work fine, the third is consistently crashing. The ones that are working access subtrees on a RAID 5 array. The failing one accesses the top level of a RAID 0 array.

Here is the log output:

I'm not sure how to proceed to help with finding the problem, but happy to assist in debugging.
