[OmniOS-discuss] [developer] Kernel Panic - Possibly SMB?

[Matthew Mabis]

I haven't been able to reproduce this issue, I believe a NC Replication (From Different Pools on the Same Host) was going on while SMB was being actively used. 

How would i look at the " In particular, look at the smb_xa_t it's working on, and the param+data buffers. Are they all there?" Any help would be greatly appreciated!

Is this reproducible? Can you show any more detail about the data structure being operated on when it panic's? 
In particular, look at the smb_xa_t it's working on, and the param+data buffers. Are they all there? 

This is just a guess, but I suspect you may have stumbled upon an instance of the bug fixed here:

Hey all wondering if someone could help me figure out what just happened, i had a kernel panic that i dont understand what caused it based on what i see in the stack it might have been SMB, if you need more like the dump file itself let me know! Any help would greatly be appreciated!
