Time conditions issue distro 4.211.64-9

Hi Everyone,
I installed distro 4.211.64-9 in december 2013 and it wordked fine till last friday.
Now when I`m trying to use my time conditions, the cpu load is going to 100% load and the machine stops to answer incoming calls… The line is dead…When switching to ringgroups or extensions the problem is gone. I did no changes at all en suddenly this happens. Its a virtual machine on a VMware 5.5 server.
Someone who recognizes this problem ?
Regards Harry

This system is super old. There has been some security patches I am guessing you have missed. Use the ‘top’ command to see what is eating your cpu

The cpu load gets up when there is an incomming call…
Grtz,
Harry
