I'll look for the core.

As part of our release process, I don't think we can release master branch of Kamailio.

Hello,

did you get core files? If yes, it would be good to see the gdb bracktraces.

Have you used the pre-loaded library workaround?

The code was not backported to branch 5.2 yet, I wanted to wait a bit and see if there are reports with good/bad results. If you want to use it, then you have to install nightly builds from master branch (development version, should be 5.3.0-pre1 at this moment).

Cheers,
Daniel

Hi Daniel,
Which apt repository can we get this workaround? Today I noticed our Kamailio 5.2.4 cored during one of our load test sessions:

Hi Daniel,

Thanks a lot for this work; it's definitely important that Kamailio
build against OpenSSL v1.1, and I'll be happy to contribute some testing
in a live environment in the coming weeks. Much appreciated.

Have a good weekend,
