This looks like much the same issue in the UNIX domain sockets. I have been looking at executing unp_gc in a deferred context, and have an initial patch which I need to test some before I send to you. Hopefully it will be ready for you to try out in a day or two. > As an added point, during boot I did see this LOR: This is likely unrelated to the problem you're experiencing, and has been reported previously. I think a workaround or fix for this may have been committed to HEAD, but would need to check the logs and see. It should be non-harmful. Thanks, Robert N M Watson
