Subject Re: [firebird-support] Classic Server User Limit
Author Steve Wiser
look in /etc/xinetd.d/firebird and make sure your instances is set to
UNLIMITED or whatever value you want... Also look in /etc/xinetd.conf
and set the instances value there as well (we also up the cps setting
for each server).
