[asterisk-bugs] [JIRA] (ASTERISK-28510) Asterisk crashing on dtls handshake

[Jørgen Ligaard Sørensen (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-28510?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=247815#comment-247815 ] 

Jørgen Ligaard Sørensen commented on ASTERISK-28510:
----------------------------------------------------

I upgraded the platform to Ubuntu 18.04 (which includes OpenSSL 1.1.1) and this has fixed the problem.
However, this does appear to be a regression from Asterisk 16.4.0 as I can only reproduce the issue on Asterisk 16.5.0

> We have observed several occurences of Asterisk crashing after recently changing our dial-plan to PJSIP. 
> We've not found any direct way to reproduce the problem, but it does seem to be restricted to high trafic hours - however there doesn't seem to be any particular threshold that causes the crash.
> For every occurence we've observed the following entries occur in the log immediately prior to the crash.
