Cam-Partition problem on MLXe

Hi

 

i see the following message in our error log

 

:Warning: cannot allocate free cache entry

 No free cache entry for new route

 

We are receiving BGP-Full routes for ipv4 and ipv6

 

I'm using  partitioning profile: ipv4-ipv6-2 and system-max value 524288

 

Did i missed something or is it not possible to use more routes?

 

Thanks for any help

SL M1: BR-MLX-MR2-X Management Module Active

show cam-profile

modify your system-max higher. X cards support 1 million routes. your interface modules must also be X cards to support 1 million routes as well.

type 'show def val' and you'll see the max possible for ip-route and ip-cache

change it to 

system-max ip-cache 1048576
system-max ip-route 1048576

bgp table nowadays is about 550k so you are dropping 30k routes.
