System freezes after "could not getpeername"

[Andreas Moroder <andreas.moroder@xxxxxxxxxxxx>]

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

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
