Not sure how you see that, maybe because one pair of 'ERROR' text is
written by 'core' (= write op) and one pair by 'tm' (= accept op)?

Okay I understand that.

This doesn't make sense to me. If 320 retries are attempted with no
write op success, then trying 3200 can't be the solution. Rather, it
must be that I have an error in the config script or some permission
problem no?

I'll keep looking and check the CN names of all certs and
permissions as well (again.) Maybe OpenSIPS 1.6.X allows a
smaller margin of error with things like TLS or certificates.
