[linux-lvm] Share getting disappeared untill system is reboot



Folks,
 
I am not sure whether this is the right list for below mentioned question. If not please direct me to the right list. Thanks in advance.
 
I am currently finding a strange issue with 2.6.18 kernel while performing the stress test with iozone on the NAS box under development. When I am trying to pump the data over iozone on the NAS box, the share on which the data transfer is progressing, gets disappeared suddenly till I reboot the system. Although this problem is seen infrequently, the frequency is quite high i.e upto 3 times out of five tests. I was able to capture following stack dump on the system.

Filesystem "dm-3": Corruption of in-memory data detected. Shutting down filesystem: dm-3
Please umount the filesystem, and rectify the problem(s)
After googling, I figured out that 2.6.19 has fixed this issue.  Any pointers on that?
 
Thanks
Sagar
