Guys,
I need some help here. I have an RB2011UiAS-2HnD with a basic config on 6.18. There are only 5 IP phones attached to this router.
SIP helper is turned off. I have 4 mangle rules marking packets to the SIP server and simple queue rules prioritizing this traffic.
I have about 100 of these setup exactly the same way without this issue.
The issue is that the SPI process is constantly at 30-40% cpu usage. Before a few reboots it was stuck at 100% but has since gone down and i am able to work on the box now.
I am not sure why this is happening. Any ideas?
