today at 02:20 I noticed that suddenly Munin stopped updating its graphs. It is not showing blank data, the whole graphs are not being updated anymore.
I run CentOs 5.7 (64) and ive installed Munin via yum. All was working, till 02:20.
First thing I did was restart Munin: service munin-node restart.
It restarted without problems or errors, but it still didn't update the graphs.
So I checked out all the log files in: /var/log/munin and apart from munin-node.log non of the files were updated since 02:20.
All that was added to munin-node.log was:
2011/12/06-02:57:19 Server closing! Process Backgrounded
2011/12/06-02:57:20 Munin::Node::Server (type Net::Server::Fork)
starting! pid(16603) Using default listen value of 128 Binding to TCP
port 4949 on host 127.0.0.1 Setting gid to "0 0"
On every restart I tried after the same message showed up.
I am really clueless to why Munin stopped working all the sudden. Any idea what I can try?

Make sure that the user which munin is running as has enough permisison to write to
