CPU 100% RB100

Upgraded two RB112’s to 3.0beta-4 and now their CPU utilization is pegged at 100%. It takes forever to load winbox / ssh.

Is there something wrong with this beta release?

From the beta4 thread:

It is rear that mikrotik have 100% CPU resources. Check your firewall to see if someone is attacking your mikrotik.

Last time, people was attacking my proxy cache from Internet Zone. Changed the proxy port and it works.

or just disable unneeded packages.
