NV2 & RB600

Sat Mar 12, 2011 8:16 am

Morning everyone,

Wanted to find out if anyone else is having issues with NV2 on a RB600. My problem in short is when I activate NV2 on the RB with ROS4.16/4.17/5.0RC10 or 5.0RC11 then my CPU usage shoots up to the 90's and eventually I get this error. Avg CPU usage is in the 70s when NV2 is disabled.
jan/01/1970 02:00:07 system,error,critical System rebooted because of kernel failure
jan/02/1970 02:00:08 system,error,critical router was rebooted without proper shutdown (cause 1)
The Reboots happens randomly.Sometimes 5 mins apart and other times a hour could go past before it decides to reboot again, but mostly it reboots itself inside 20 mins. Even if I have the nv2 protocol switched off on the wireless interface it still does random reboots. The RB becomes more stable if I disable the nv2_wireless package and use the standard package.

I'm running 4 interfaces on the RB of which one is a sector on which I want to run NV2. NV2 is great and increases the throughput on the sector, but the cost seems to be a very unhappy RB600.

The RB runs OSPF and has mangle rules.

I'm not so sure if this problem is just because the RB600 can't handle the added CPU requirements of NV2 or if it's a ROS problem with RB600s. So some guidance and experiences would be much appreciated.

I have a supout.rif file if that would help to get some answers.

Hello, i use R600A with R52n 4.16(2.27fw) wireless-nv2 package, in mimo 40MHz and ap-bridge->station-wds mode without any problems. CPU usage normal.

Hunted, please email support@mikrotik.com with the support output file which is created after that kernel panic when you have RouterOS v5.0rc11 installed.
