Are you exporting a LUN to one client or multiple clients at the same time?

Are you doing any IO to the iscsi LUN?
If not, then we normally saw this with a older version. It would start
at dm-multipath initialization and then just continue forever. Your
package looks like it has the fix:

Allow some commands to run while taking lock
so we should not be seeing it.
Could you turn on tcmu-runner debugging? Open the file:
/etc/tcmu/tcmu.conf
and set:
log_level = 5
Do this while you are hitting this bug. I only need a couple seconds so
I can see what commands are being sent.
