Yes it ran, but at the end at 22:17, not at 22:13 when the first errors 
appeared. From freshclam.log:

... and then the next entry:
--------------------------------------

There were also a few incoming e-mails during that time which were scanned via 
clamav-milter and clamd. Could that have an effect?
