[gfarm-discuss:11167] connection limit exceeded

[Ryo UMETSU <u-ryo@xxxxxxxxxxxx>]

Hello,

I'm using Gfarm 3732-1 on i386 through "syscall hook library".
I'd like to run parallel jobs on GfarmFS. Several jobs worked well,
but more than 12 (in my case) jobs couldn't find /gfarm directory.
I think this may be the cause in the syslog (/var/log/messages):
gfsd[10266]: gfarm_pgsql_initialize: FATAL:  connection limit exceeded for non-superusers
gfsd[10266]: unknown address family 1: FATAL:  connection limit exceeded for non-superusers

My questions are,
1. Can I expand or avoid this limitation?
2. If yes, what should I do?

Thank you in advance.
