Ip Route Cache reach the maxium

Hi,

I have an issue with the Ip route cache that reach the maxium and the retour come unresponsive. My maximum cache-size is 1048576 and I can only do one week with this, every minutes the cache grow up and never go down. I tried to find somewhere to flush the cache but no success. The only way I found is to reboot the router and I’ll be good for another week.

I’m using Mikrotik under a Vmware Virtual Machine and I have the version 6.6 of Mikrotik OS.

Thank,
