Richard Mudgett commented on ASTERISK-26043:
--------------------------------------------

Core files are *useless* except to the machine that generated them (or an exact clone of the machine which is unlikely anyone else will have).

> Im getting ramdom crashs in my asterisk boxes, at this point i try to dig what type of call make it happen but i don't have any clue what is happening here, i collect the proper core dumps and logs in other to determine what is going here,
