Hello,

we have a old  2.4.19-64GB-SMP server. Today it freezed twice and me had 
to reboot via sysreq.

In messages I found

Aug 27 17:22:08 galileo2 -- MARK --
Aug 27 17:38:01 galileo2 inetd[1397]: could not getpeername

Aug 27 18:07:52 galileo2 inetd[1397]: could not getpeername

Can anyone please tell me what could be the reason for this error ?
Is this a DNS problem or a file-nr problem ?

Thanks
Andreas
