One thing that comes to my mind is that one tgtd process dies when initiator wants
to read data and tgtd can't "deliver" it immediately (i.e., I/O "frozen" because of
SATA resets/exceptions/timeouts). It doesn't happen always on such SATA timeouts and
is therefore hard to reproduce.
TMF (an initiator tries to abort a request due to timeout) might be
related with your problem. I'll dig into it this weekend.

I reported a similar issue in June 2008 - see the thread titled
"disk kicked out of RAID -> tgtd segmentation fault":

Can it be related somehow?
I thought that I fixed the bug in the above thread.
Yes, it was fixed. I just wanted to tell that the symptoms are similar.
