[asterisk-bugs] [JIRA] (ASTERISK-21738) Segfault On Realtime Queue Members Processing

[JoshE (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-21738?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=206021#comment-206021 ] 

JoshE commented on ASTERISK-21738:
----------------------------------

Quick additional update, though I haven't really traced this all the way through.  Issue is with the determination that is made for the realtime_ringinuse_field check.

Patching this:

       if ((config_val = ast_variable_retrieve(member_config, interface, realtime_ringinuse_field))) {

To this hardcoded value:

       if ((config_val = ast_variable_retrieve(member_config, interface, "ringinuse"))) {

In app_queue.c resolves the core dump, at least temporarily.

As some further information, I have about 150 entries in RT queue_members and 2000 peers that are being loaded from realtime in this configuration.

For whatever reason, on some threads, the realtime_ringinuse_field isn't set and that null value causes the crash.
