| Level | Kleine Änderung |
| Klasse | Bugfix |
| Kompatibilität | Kompatibel - benötigt kein manuelles Eingreifen |
When monitoring hosts using piggyback data an exception could occur when a host is checked by different processes at the same time. This could happen e.g. when the running core updates the piggyback data while a manual "check_mk -nv [hostname]" call also tries to update this data.
The fixed exception looks like this in cmc.log:
