Hmm, strange. It's the first time I've heard of such a problem, ever. Can you see anything out of the ordinary in /var/log/munin/*.log?

The emails contains information of the lock files existing, I assume?
Yeap.
Are you able to reproduce the problem at will, or was this a one-time occurrence? If so, could you try
It's totally repeatable. When I kill all pids of munin-*, and wait for next cronjob, it happens again.
"sudo -u munin /usr/share/munin/munin-graph --debug" and mail me the output? I have a suspicion the spinning happens somewhere in RRDtool..
Yeap, I can although it's quite big, I have just run it and it ends ok with no errors in fact. One more important thing. This host behaves as a server and a client. I mean: I have two locations. This is one, and is graphing itself and some hosts. And I have a second machine, that graphs the above and some others hosts. Maybe that's an issue of cross-updating or sth. Other weird things is that every time it happens, there are two processes of munin-cron run at the exactly same time. -- Best regards, Radek Antoniuk
