Hi Daniel
Running on a LAN with no firewalls enabled,
limits can be from kernel, selinix, mysql server a.s.o. not only from
firewalls.
will try you suggestion
though first thing tomorrow morning, what are the implications of
running children=1 ?
This will create only one worker process (not advisable for production
in long term, just for testing) -- in this way there should be very few
mysql connections opened, revealing if there is a problem or not with
the number of connections and the short period to create them.
Cheers,
Daniel
Thanks

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

complete to trace the issue. Did you see the same Errors every time it fails
!?

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.

Hi,
forget the whole list of errors and just resolve the DB connectivity
between
the Kamailio server and DB server first .
> 27(24762) ERROR: db_mysql [km_my_con.c:109]: driver error: Can't
> connect to MySQL server on 'xxxxxxxxx' (4)
try connecting to the remote DB server 'xxxxxxxxx' from linux shell i.e
# mysql -u<user> -p<passwd> -h 'xxxxxxxxx'
Regards,
Sammy
