[Serdev] CVS:commitlog: sip_router/modules/domain domain.c

[Vaclav Kubart]

Hi,
this problem can be related to improper process initialization. We
solved some time ago problem like this - database connection is
initialized in child_init, but CTL module (responsible for handling
binrpc) created a new process which didn't call child_init (or called
with a rank for which was not created DB connection, I don't remember
exactly), so the DB connection was not initialized for "binrpc" process
and thus DB operations called via binrpc failed.
