Thanks badlop ,

It was great help for me and i become able to solve this crash which was caused due to local_config.

The first error reason shown

badlop — Wed, 23 Dec 2015 21:43:33 +0000

The first error reason shown in all those lines is this one:

{error_info,{badarg,[{ets,lookup,[local_config,{listen,global}],[]}

It probably indicates that the Mnesi table (an internal Erlang database table) called "local_config" does not exist. This table is created when ejabbed is started, and the table is never deleted, because it is important.

How can it be that this table does not exist? Check your log files, maybe there is a previous line with some clue.
