Do i get it right : The socket(-buffer) used by postfix wasn´t
read/cleand fast enough an therefor the postfix daemon could only write
a part of its status?
If this is correct i wonder why this occurs in the middle of the night
with 2-3 msg./h load.
Can any other process block the socket operation?
I´m not a programmer so it isn´t obvious for me where to search.

This means i can ignore the warning without getting sleepless :-)
