Okay thanks.
The only reason I ask is that I've rebooted the Linux SAN a few times to
get past an error that occurs once or twice a week.
I'm provisioning disk to ESXi 5.0 servers and have some test VMs on it.
When the error occurs the logs look like the following:

The 'Detected NON_EXISTENT_LUN Access' error then persist until I reboot.
I'm not sure if there is something I can do to avoid this error or not.
I was hoping the fixes in the master branch may have been the solution :)

Here's another more recent one as well for good measure:
