I cannot seem to find that specific commit (even in the latest official kernel git). I was trying to see if it was in any of the newer Ubuntu kernels (4.10 or 4.13) as it would be easier to install one of those that to try to recompile I myself.

It seems like most of our tipc-discussion subscribers, (including myself, the project owner), were automatically removed from the lists at some recent moment. Another screw-up by SF… As far as I can see, you are missing the following: commit d4091899c9bbf (“tipc: hold subscriber->lock for tipc_nametbl_subscribe()”) This was delivered to 4.5, but doesn’t seem to ever have made it into 4.4. I am surprised, because you seem to have reported exactly the same issue on March 22d last year, and I believed it was fixed. Do you apply patches yourself, so you could try this one? If it solves the issue and applies cleanly I could post it to stable_4.4.

A bug that I thought had been fixed is rearing its ugly head again in latest Ubuntu 16.04 LTS kernel (4.4.0-97) It is happening to me quite frequently (2-3 times a week). The application where this happens uses lots of short lived sockets, and also lots of short-lived connections to the topology server.
