After upgrading to Version 5 release, before using 5 RC7, our load CPU increase very high, to 80 - 95 %, and often after changing some queue, the router like freeze for few second.

These are our capture of profile, when high CPU load accured :

> /tool profile
NAME CPU USAGE
firewall-mgmt all 0%
ethernet all 0.1%
queue-mgmt all 0%
console all 0%
eoip all 0%
firewall all 27.8%
gre all 0%
winbox all 0%
logging all 0%
management all 16.1%
idle all 30.7%
profiling all 9.3%
queuing all 13.7%
routing all 1.7%
unclassified all 0.1%

For your information, there just few basic script in firewall, like drop input invalid, and drop forward invalid, and accept estabhlished connection..

Thanks,

Got problems on 5.0 on RB1000.

The router runs ok for a couple of hours, but after 3 ou 4 hr running OK, it starts the cpu starvation (100%) and all PPPoE tunnels goes down.

Didn't able to downgrade, or even uninstalling a 5.0 package (tried uninstall ipv6 for example).

All tries is followed by:

Send the supout and waiting for an emergently answer, because we are unable to downgrade and having heavy troubles at my core network.
