CSCvc16197 - BGP origin-as validation enhance table walk during validation

Does anybody see the same behavior on ASR9K series with high periodical CPU utilisation as described in CSCvc16197?

I see hourly "palisade" per validator project on ASR9001.

My temporary workaround is highly increased timers. This operation I done on RPKI local cache validator projects. Maximum possible refresh timer on router is 3600 seconds.

On the picture(last day monitoring) you can see CPU utilisation without increased timers. Each router has 3 full-view table, 2 big IX, all other private and downlink peerings. IOS XR version is 6.6.
