Hi, I'm running postgres 8.3.17 on a redhat linux mips derivative and I've observed a postgres crash and the subsequent messages in my postgres debug log. 2011-12-21 19:08:49 UTC - LOG: shutting down 2011-12-21 19:08:49 UTC - PANIC: concurrent transaction log activity while database system is shutting down 2011-12-21 19:08:49 UTC - LOG: background writer process (PID 1423) was terminated by signal 6: Aborted 2011-12-21 19:08:49 UTC - LOG: terminating any other active server processes I'm having trouble understanding what could cause this. I've looked through the postgres sources and I don't understand what is "shutting down" since this happens on a live system where no stop has been requested. Also It happens very infrequently and I don't yet know how to reproduce it. I'm happy to provide more information. thanks in advance for the help! -HH -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
