[GENERAL] postmaster deadlock while logging after syslogger exited

2017-11-06 Thread David Pacheco
Hello, I ran into what appears to be a deadlock in the logging subsystem. It looks like what happened was that the syslogger process exited because it ran out of memory. But before the postmaster got a chance to handle the SIGCLD to restart it, it handled a SIGUSR1 to start an autovacuum worker.
