What tools are you running ?

I am having the same problem on Fedora.

 nslookup cool.com
Note: nslookup is deprecated and may be removed from future releases.
Consider using the `dig' or `host' programs instead. Run nslookup with
the `-sil[ent]' option to prevent this message from appearing.
socket.c:1111: internal_send: 192.168.0.35#53: Invalid argument
socket.c:1111: internal_send: 192.168.0.35#53: Invalid argument
;; connection timed out; no servers could be reached

4 identical boxes. All running Fedora Core 1 but the problem appears to be on only 2 of them.

I verified the problem with vserver-utiles .29 and the folowing smp kernels:

vmlinuz-2.4.23-vs1.22
vmlinuz-2.4.24-vs1.22
vmlinuz-2.4.22ctxsmp-17c

Kernel vmlinuz-2.4.23-vs1.22 was compiled in one machines and the moved to the other boxes. The machine I compiled on has the socket.c problem. 2 of the other 3 boxes nerver reported the problem and last one had it untill I untared the moved kernel and modules again.

vmlinuz-2.4.22ctxsmp-17c ran perfectly on the same machine on rh7.2 with no problem.

I am beginning to think it is some obscuer tools issue.
