[asterisk-bugs] [JIRA] (ASTERISK-20994) asterisk crash on module change

[Matt Jordan (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-20994?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=202304#comment-202304 ] 

Matt Jordan commented on ASTERISK-20994:
----------------------------------------

Did you unload the old app_confbridge module before removing it?

I'd expect bad things if you blow out a shared object library while Asterisk still technically has it loaded in memory.
