Hrm. Does a socket in the TIME_WAIT state count against the number of open file descriptors? Certainly, it shouldn't count against the per-process limit, as the process has already closed it. > Do you have any advices to get rid of this TIME_WAIT problem ? > Our client runs on the same machine as the postgresql server. > Would it be possible to use PF_UNIX sockets ? Yeah, actually that's the default, if you just run "psql" with no parameters. It looks for a socket in /tmp/.s.PGSQL.5432. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise Postgres Company -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
