Shalom Paul,

You are having DNS name resolution problems.

Check the servers defined in /etc/resolv.conf provide proper answers and can be reached.

IF not change them.

What is your os version & ARPA patch?

is it permanent or just sometimes?

Are you using 3rd party application like centrify one?
what do you have in nsswitch.conf

usually it means that a socket have been closed in inetd unexpectedly.

The only know case is with third party nss services installed. - they close a socket they don't own-

Hi Paul,

No
clearly your inetd had closed some of its sockets unexpectedly.
what do you have in your /etc/nsswitch.conf?

is it something which happens often or just once?

Hi,

What i did is i stopped snmp using the command "/sbin/init.d/snmpdm stop".
I found no nsswitch.conf in /etc but:
nsswitch.compat
nsswitch.files
nsswitch.hp_defaults
nsswitch.nis
nsswitch.nisplus

regards,
PAUL
