Strange Errors in named.log

[grahamcrabb at gmail.com]

I have a fairly simple unloaded server runnign primary only zones on
bind 9.3.1 it seems to be working ok, however whenever I restart bind,
it does all the normal loading of zones and sending notifies and then I
get the following errors repeated about 20 times:

29-Jun-2005 16:50:27.311 socket() failed: Interrupted system call
29-Jun-2005 16:50:28.361 socket.c:1415: unexpected error:

Anybody any idea what might be causing this?

TIA

Graham.
