It's annoying that the buildfarm animals running on older versions of Solaris randomly fail with "Connection refused" errors, such as in today's example: http://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=castoroides&dt=2012-09-15%2015%3A42%3A52I believe what's probably happening there is that the kernel has a small hard-wired limit on the length of the postmaster's accept queue, and you get this failure if too many connection attempts arrive faster than the postmaster can service them. If that theory is correct, we could probably prevent these failures by reducing the number of tests run in parallel, which could be done by adding say MAX_CONNECTIONS=5 to the environment in which the regression tests run. I'm not sure though if that's "build_env" or some other setting for the buildfarm script --- Andrew?
Yes, in the build_env section of the config file. It's in the distributed sample config file, commented out. cheers andrew -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
