The problem is that it is never removed. I waited for at least 30 minutes.

I mean, 'vconfig rem' on another interface stucks if the previous vconfig
has not finished, and it never finishes. So I cannot check if other vlan
interfaces have the same 'refcnt' problem. So far I tried 'vconfig rem' on
two vlan interfaces and I have a dozen.

Again, the problem only happens after I notice surprisingly high LA (30
instead of 2-6) and interactive slowness. When it happens, I check network
usage, disk usage, cpu usage, mem usage - they are normal or even lower than
usual.

The server is running transparent squid and named. The last kernel version
was 2.6.27.21 and it did not have this problem.
