Hello,<br>
<br>
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.<br>
<br>
Cheers,<br>

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