Hi all,
I was wondering what is the max children I can spawn. When I set children = 32 I got this error when doin openserctl moni:
Error opening openser's FIFO /tmp/openser_fifo Make sure you have line fifo=/tmp/openser_fifo in your config
Seems like openser or my system can't support that many children? I read that in the core cookbook that max children was 32. Wonder why it crashed on my system. Its a Dell Server, specs should be Pentium 4 3 Ghz with 1 GB ram. I think this spec should be enough to support 32 children.
Here is the debug error.
51(4998) ERROR:domain_db_init: cannot initialize database connection 51(4998) 52(5000) new_connection: Too many connections 52(5000) ERROR: child_init(50): Error while connecting database 52(5000) ERROR:init_mod_child: Error while initializing module usrloc, rank 50 52(5000) init_children failed ERROR: domain:child_init(): Unable to connect to the database
What am I suppose to do to fix it? I'm using mysql database. Is it because mysql needs to support more connection? How am I suppose to change that? Thank you

Hi Kenny,
the limitation is not in openser or system, but in your mysql server configuration - it does not accept such a high number of connection (as required by 32 children).
You need the configure the mysql server to accept a higher number of connections.
