Today, lorikeet failed with a new variant on the bgworker start crash: https://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=lorikeet&dt=2017-06-21%2020%3A29%3A10
This one is even more exciting than the last one, because it sure looks like the crashing bgworker took the postmaster down with it. That is Not Supposed To Happen. Wondering if we broke something here recently, I tried to reproduce it on a Linux machine by adding a randomized Assert failure in shm_mq_set_sender. I don't see any such problem, even with EXEC_BACKEND; we recover from the crash as-expected. So I'm starting to get a distinct feeling that there's something wrong with the cygwin port. But I dunno what. regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
