Thanks Bogdan for the detailed reply.
I implemented your advice.
Those error messages are now gone.
But seeing a new error now; not sure if it is related to that...
ERROR:core:io_watch_del: BUG - trying to del fd 36 with flags 2 1
Any advice?

Hi,
Those messages say that OpenSIPS tried to open a TCP connection to a party which does not respond -> there was a timeout for connect in 10 seconds. Because of this blocking in connects, there were not more opensips workers available to handle other traffic.
So what you need to do is :
- minimize the impact of the blocking connect - see my previous email on reducing the connect timeout
- you may configure OpenSIPS not to open new TCP connect (but to reuse the existing ones, open by clients). See tcp_no_new_conn_bflag
http://www.opensips.org/Documentation/Script-CoreParameters-1-11#toc96
- try to understand the SIP patterns where such TCP connect fails so you can avoid them at script level.
Regards,

Hi,
The following lines are repeating in the log.
ERROR:core:tcp_blocking_connect: timeout 10 s elapsed from 10 s
ERROR:core:tcpconn_connect: tcp_blocking_connect failed
ERROR:core:tcp_send: connect failed
ERROR:tm:msg_send: tcp_send failed
INFO:core:send2child: no free tcp receiver, connection passed to the least busy one
Any guess, what could be the reason?
Best
