I've reported this in the past, and have seen a related thread but no
resolution so far and I'm still seeing it. Any help really would be very
much appreciated.
We have three thumpers (X4500):
* thumper0 - Running snv_76
* thumper1 - Running snv_121
* thumper2 - Running Solaris 10 update 7
Each has exactly the same disk and zpool configuration, and was bought at
the same time.
thumper0 sends snapshots hourly to thumpers 1 and 2. It is relatively
stable. It's running a very old firmware but we aren't keen to update as
this is our live service system.
thumper1 regularly hangs during a receive - maybe after 1-2.5 days of
hourly receives. All zfs commands on the filesystem receiving the data hang
unrecoverably and only a hard system reset or a reboot -n (do not sync
disks) will allow the machine to return to service.
It's running the most recent system firmware.

What can I do in an attempt to find out what is causing these lockups?
I have a case open for this problem on Solaris 10u7.
The case has been identified and I've just received an IDR,which I will
test next week. I've been told the issue is fixed in update 8, but I'm
not sure if there is an nv fix target.
I'll post back once I've abused a test system for a while.
