Re: Bug report: open-iscsi hangs system
Hi! I don't know if that helps, but for an old version of open-iscsi I also saw the message iscsid: semop up failed 22, but it did no harm to the system.

Bug report: open-iscsi hangs system
Just by coincidence I came across the following behaviour: Setup: Fedora 9, fully patches OS with latest git version of open-iscsi, kernel 2.6.27.15-78.2.23.fc9.i686. Target is tgt, latest git version. Normally I am able to log into the tgt target, no problems.

Normally I run a little script which defines the target for the tgt daemon, this time I forgot. So no actual target defined. When I tried to log into the target, open-iscsi hangs, and in fact it freezes the whole system. If the iscsi port was closed, ie not even the daemon started, open- iscsi hangs, but no freezes. I only see the following messages in my /var/log/messages: Mar 1 15:27:02 orange iscsid: semop up failed 22 --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups open-iscsi group.

This time I started up tgt, but had forgotton to define a target

I just tried it here and could not replicate it. Could you run your test

Could you run iscsid with

debugging
make DEBUG_ISCSI=1

If the iscsi port was closed, ie not even the daemon started, open-
iscsi hangs, but no freezes.
What do you mean by hangs? You run iscsiadm -m -l and that never
completes? The timeout for this might a little long now. It could be
around 2 minutes.
