Hi, Bruce.
I'm not sure how we solved that, but it was working fine in NT 12.47.
We needed some new features so we migrated to NT 14.37 - now, the problem started again.
With the server sitting idle, just answering "pings", it GPFs each 6 or so hours.
Basically, same GPF as this old case.
I'm sure all the dlls are matching NT 14.37, libcrypto-3.dll is 3.5.1.0, LibSSL-3.dll is 3.5.1, clanet.dll is 14.37.0.0, all in the program's folder.
Note in the GPF there is no mention of any other program, just clanet.dll and clarun.dll.
Is there any other resource I should check?
Why is it calling SSL_OUR_SERVERSWITCHTOSSL? Our "unsecure" port is closed, there is nothing coming from there (all connections are TLS).
Is this needed? Can be disabled somehow?
