Hello list,

today I experienced the following for the first time :

'0x114af2c0'


Question 1 : What can be causing this ??
Question 2 : What can I do when this happens ? Because Asterisk was no 
longer responding untill I rebooted the server. What is the right way to 
handle this extreem situation ?
Question 3 : How can I avoid this situation from happening again ?



Kind regards,
Jonas.
