Is there any other explanation why we should be thinking of bumping it to like ulimit -n 50000 ( Add ulimit -n 50000 to the start of whatever you use to start pgbouncer (init script, etc..)) even though we are not reaching 4096 max value > > Regards > Prabhjot Singh > Hi, Try attaching to the pgbouncer with strace and see if you are getting any particular errors. Do you have a /etc/security/limits.d directory? And if so, what is in it? We found a nice default ulimit of 1024 for all non-root users. :( Regards, Ken -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
