[asterisk-users] High load on asterisk servers

[Stefan Schmidt]

Maybe this happens if you have a short delay to your dns servers. This 
could increase the load very fast and after some seconds it might be 
over again.

I have installed a dns recurser with own caching on all of my asterisk 
servers and now everything runs much more smoothly.

best regards
