Re: [SR-Users] Intermittent start up issue

Hello,

check also for limits in the system/firewall, maybe there are limits on new connections per second. Try with children=1 and see if it happens again, if not, then it is something that blocks many new connections in short time.

Cheers, Daniel

Hi
Thanks for your input, but as said this works at times yes and times
now so I am not sure it is a definite DB issue, the servers are in the
same LAN, and there are other modules that use the DB string that work
when launched before this one while this one does not work.
