[SR-Users] Kamailio 5.4.3 crash at SSL error

[Igor Olhovskiy]

Daniel,

Will try to update, thanks!

It's only SIP traffic being used in TLS/WSS flavor.

But as I've mentioned, this happened only once for about 3 months of 
non-interrupted running and I don't see a way to reproduce it. Will keep 
an eye on it.

Regards,
Igor
