Hash: SHA512


 I have newly installed 10-STABLE server which sometimes (every second
dat on average) sends me messages like this (TWO AT SAME TIME!):

====
From: Cron Daemon
Subject: Cron <operator_at_host> /usr/libexec/save-entropy

unlink: saved-entropy.8: No such file or directory
mv: saved-entropy.7: No such file or directory
====

and

====
From: Cron Daemon
Subject: Cron <operator_at_host> /usr/libexec/save-entropy

mv: rename saved-entropy.6 to saved-entropy.7: No such file or directory
mv: saved-entropy.5: No such file or directory
mv: rename saved-entropy.4 to saved-entropy.5: No such file or directory
mv: saved-entropy.3: No such file or directory
mv: saved-entropy.2: No such file or directory
mv: saved-entropy.1: No such file or directory
