Hello!

I've a problem with privvmpages which i can't solve. privvmpages are failing directly after booting up the VE and when the VE is runnnig. I set up the limit higher and higher but it still fails.

What do you exactly mean? I've this problem on about 20 VE's - they all run a normal debian image - nothing special.

at the moment it is already set to 12GB and current value is only 1.1GB - i think this should be enough - not?

The following software runs:
qpsmtpd
qmail
stunnel
apache
proftpd
mysql5
mysql4
munin-node

The failcnt is also high directly after boot even when nobody has connected to the ve. Exactly the same image runs also fine on an old PIII with 512MB of RAM.
