eip 0804f0b5 esp 77c43ff0 error 4
Hmm, unfortunately, I can't reproduce this.
Strange, it is 100% reproducible here, on a x86 system. I didn't try 64
bit.
I just do dmsetup suspend / wait a few seconds / dmsetup resume, while
the initiator is reading data, and tgtd segfaults.
It crashes if I wait about 120 seconds or more.
If I wait less, it does not crash.
I made sure that I wait about 120 seconds but I can't reproduce this
(it takes about 120 seconds to see the abort and close messages in the
log.
We should not see a series of 'conn_close' messages. Something
unexpected happens at your box.
Can you try this and send the log? It doesn't fix the problem but
gives more information.
once it didn't die after 120 secs and produced - this happened before the crash I pasted earlier:
