you can try to do strace -fF -o netstat.trace netstat -pantu
and check/upload the resulting netstat.trace file somewhere
maybe it gives some clue to the folks combining Linux-VServer
with grsec ...

if it happens with vs2.2.0 (without any other patches) then
it is considered a Linux-VServer issue/bug and will be fixed

here on a test server with vs2.2.0, I get the following:
 
# netstat -pantu
Active Internet connections (servers and established)
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name
