I use command vzcfgvalidate to check is the conf file correct or not like in guide.

I receive follow results:
# vzcfgvalidate /etc/vz/conf/808.conf
Error: tcpsndbuf.lim-tcpsndbuf.bar should be > 768000 (currently, 1000)
Error: othersockbuf.lim-othersockbuf.bar should be > 409600 (currently, 40000)
Warning: tcprcvbuf.lim-tcprcvbuf.bar should be > 768000 (currently, 1000)

BUT, in conf file:
TCPSNDBUF="769000:770000"
TCPRCVBUF="769000:770000"
OTHERSOCKBUF="409600:449600"

and command # vzctl exec 808 cat /proc/user_beancounters

Hi,

1.

Quote:

(tcpsndbuf.lim-tcpsndbuf.bar)

- is the difference of that values.
Sign "-" means minus. So your difference equals to tcpsndbuf.lim-tcpsndbuf.bar = 770000 - 769000 = 1000

2. The good explanation of this demand you can find at this page
http://wiki.openvz.org/UBC_consistency_check#Send_buffers_sh ould_have_enough_space_for_all_sockets

2. I agree with you that the form of this error is not quite convenient and can be misleading.

Thank You!

Thanks a lot!

P.S.

May be to write for example
tcprcvbuf.lim-tcprcvbuf.bar should be > 768000 (currently, 769000-768000=1000) will be more clear?
