Munin-cron meldet fehlende Plugins

[GwenDragon]

Ich verwende auf meinem VServer munin-1.4.5-4.el5.noarch

Zeitweilig (3-4 mal am Tag) meldet mir cron folgendes:

[FATAL] There is nothing to do here, since there are no nodes with any plugins. Please refer to http://munin-monitoring.org/wiki/FAQ_no_graphs at /usr/share/munin/munin-html line 38

Die Plugins zeigen aber selbst keine Fehler, das habe ich schon mit munin-run getestet.

Das munin-graph.log zeigt zu den Zeiten der cron-Meldung keinerlei Services, für die Graphen erzeugt wurden.
Dafüre existiert im munin-update.log ein Timeout:

2010/12/13 03:50:11 [WARNING] Call to accept timed out. Remaining workers: de;server2.de
2010/12/13 03:50:21 [WARNING] Call to accept timed out. Remaining workers: de;server2.de

Ich habe mal in den Logs gegrept:

[root@server2 munin]# grep "03:50" munin-*.log

Sind solche Timeouts bei munin auf einem VServer normal oder sollte sowas nicht vorkommen?
