[asterisk-bugs] [JIRA] (ASTERISK-22350) DUNDI - core dump on shutdown - segfault in sqlite3_reset from /usr/lib/libsqlite3.so.0

[Corey Farrell (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-22350?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=209556#comment-209556 ] 

Corey Farrell commented on ASTERISK-22350:
------------------------------------------

Using Ctrl-C to shutdown causes SHUTDOWN_FAST.  Modules are not unloaded for SHUTDOWN_FAST or SHUTDOWN_NORMAL, but ast_register_atexit callbacks are run.

The 14k pastebin.txt shows that thread #1 is DUNDI trying to use ast_db_gettree.  Thread #12 is close_logger() waiting for the logger thread to end.  This means that astdb and most other things in the core have already been shutdown by ast_run_atexits.  Since asterisk exit's very shortly after ast_run_atexits() this is difficult to reproduce.
