Not yet, but I really need to as I have a similar problem. For me
it happens with all vservers bar one, and my eyes are hanging
out trying to see any difference between them. All *conf files
have the default: S_FLAGS="lock nproc" and S_CAPS empty.

The faulty vservers are also difficult to contact - eg httpd, sendmail,
fptd all take a long time to respond. I would suspect routing problems
except that they all seem to have the same style of configuration.

How have you set up your routes? Eg, "IPROOTDEV=eth0", or
have you kept the routes in the main server instead?
