GPF on Line=1774 Proc=SSL_OUR_SERVERSWITCHTOSSL

[jlavera]

Hi, all

I'm having a repetitive GPF as this:

1303F10Ah    Line=1774    Proc=SSL_OUR_SERVERSWITCHTOSSL@F  Src=netdl020.clw     Module=J:\RestServer\CLAnet.dll 11.53.0.0

Any idea what this can be?

Jorge Lavera

[jlavera]

This also happened before the last upgrade, in line 1769 of netdl020.clw (clanet.dll) version 11.43.0.0, same Proc=SSL_OUR_SERVERSWITCHTOSSL.
Bruce, any idea what is in that line? Our rest server is failing every half an hour with this; no special calls or overload.

Thanks,
Jorge Lavera

Did you double check that your ClaNet.DLL version matches your NetTalk version?  That can cause weird behavior.

[jlavera]

Hi, Don.

Yes, the version reported by clanet.dll matches the respectives NT versions installed. Triple checked.

Hi Jorge,

since this is an unusual GPF, the error is likely in the run up to that specific line.
So it would be a good idea to post the whole stack trace from the GPF

Hi, Bruce.

[Bruce]

It's calling into OpenSSL, into SSL_New.
So it happens when a new connection is made.

Perhaps one of your OpenSSL's is not installed in the exe folder correctly. See
https://www.capesoft.com/docs/NetTalk11/NetTalk.htm#DeployingAtlsClientOrServer

If that doesn't help it'll need some extra debugging added to your system - but to do that you'd need to be on NetTalk 12.

Cheers
Bruce

[jlavera]

I'll check, thank you, Bruce.

[jlavera]

We are still having the GPF after the upgrades, about 15 minutes after starting. We made sure every file is updated.
Help!

Next step is for me to TeamViewer your server to see what is happening.
Usually I'd say "email me the details" but email is offline at the moment, so catch me on skype and we can set it up.

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?
