I also realize that. I also know that running netstat would lock my
particular server.
 Sorry if this is not vserver-unrelated. I would like to know what could
trigger such a reaction in Linux when there is no active user. I don't
normally touches netstat, and the server usually goes down only after at
least a few hours. Is there any possibility that some processes could be
using /proc/net/tcp periodically, thus causing the lock up? The virtual
server is an FTP server with only a few connections, and my main server
is a standard Redhat 7.1 install.

There is an issue with kernel 2.4.18ctx-9. It locks the server completly
accessing /proc/net/tcp (or doing netstat) for one. Other kernels are
fine such
as 2.4.18ctx-8. We do not know yet why ctx-9 is buggy as it differs very
little from ctx-8.
