> Crash occurs when starting Asterisk and we have 2 realtime sippeers mysql connections configured (with priorities 1 and 2) and there is a sippeers (sipfriends) schema WARNING logged.
> In our case it was column ipaddr varchar(15) was less than 45
> After we altered the table and set ipaddr to varchar(45) - no crash anymore
> Also if there is only 1 realtime connection but still with ipaddr varchar(15) - no crash
> I can provide some debugging output
