You could check your <VEID>.conf with vzcfgvalidate. But I think there is
quite a risk when giving one of your CT’s unlimited resources. If you want
to read-out the UBC’s from the node and see when one fails I could recommend
you a very good script I’m using myself;
http://wiki.openvz.org/UBC_failcnt_reset There is no need to reset the
value’s inside your CT.

I also think that these UBC settings are not consistent. Especially when you
have all containers configured with these same UBC settings you will have
soon or later problems.



See: http://wiki.openvz.org/UBC_consistency_check and other pages on the
WIKI.



Kind Regards,

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
