[Kevin Harwell (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-28845?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=250488#comment-250488 ] 

Kevin Harwell commented on ASTERISK-28845:
------------------------------------------

Regarding the "ivr group" crashes within lua.

Those crashes appear to be down in lua itself, and seem to occur at different places. Makes me think either bad data is being passed in, or some memory is getting corrupted.

Did this just started happening? What might have changed from before? Did you upgrade _lua_? Asterisk (although according to the log _pbx_lua_ has been modified in a couple of years)? The dialplan?

Anything in the log? Error, warning, or notices? If you haven't already try enabling debug and verbose, and attach those logs and associated crash.
