[asterisk-bugs] [JIRA] (ASTERISK-27412) asterisk 15 + ubuntu 16 + realtime chan_sip - segfault

[Richard Mudgett (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-27412?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=239957#comment-239957 ] 

Richard Mudgett commented on ASTERISK-27412:
--------------------------------------------

valgrind can prevent crashes by how it operates and still find things.

The patch adds a new option to disable the media frames caches.  The default of the new option has the caches still enabled so you need to explicitly set the option off in asterisk.conf as indicated by ASTERISK-27413.

> I've installed Asterisk 15.1.0 on Ubuntu server 16.04. I configured realtime sippeers (tried via odbc and res_config_mysql - all the same). And asterisk core crashes after 20-40 minutes of working.
