Load above normal, qmail, bogofilter, increase CPU?

Hello,

on my VPS load is above normal. It is around 2.00 all the time.
But VPS has assigned:
1000 CPU units, one core.

Does it mean VPS needs faster CPU, or can balance high load any other way?

The load is 70% used by process: bogofilter

the maillog file is full of:

vps qmail: 1383152935.943223 delivery 420078: deferral: Uh-oh:_.qmail_has_prog_delivery_but_has_x_bit_set._(#4.7.0)/

some of my .qmail files have execution permissions. when i removed it by chmod -x file

it stopped say this, but instead:

vps qmail: 1383153288.190979 delivery 421273: deferral: maildrop:_Unable_to_open_mailbox./

:cry:

Hello, on my virtual private server, 70% of CPU is used by bogofilter
i have qmail installed and "maillog" file dont shows any new mails activity.

Please how to discover why bogofilter is so high?
