I read that UBC page already and used it to set these values.

No, all my containers do not have the same UBC settings, they were set
depending on how much resources each container should have.

Please let me know where any of the values in my conf file conflicts with
the UBC recommendations.

I do understand that they may need to be fine tuned in each case, but
that's basically what this question is about :)

So basically at this time I have two questions I don't understand:

1) how is it possible to have physpages hit the limit when top never shows
more than about 75-80% of the memory used?
2) how did dcachesize hit limit when both df -i and df -h shows plenty of
resources - and haven't been close to limits?

Could the values in the beancounter file be old? Is there a way to reset
them (without restarting the CT) ?

Best,
Rene
