| Component | Core & setup |
| Title | Fixed possible exception in cmc.log when working with piggyback data |
| Date | Jul 10, 2017 |
| Checkmk Edition | Checkmk Enterprise (CEE) |
| Checkmk Version | 1.4.0p9 1.5.0i1 |
| Level | Trivial Change |
| Class | Bug Fix |
| Compatibility | Compatible - no manual interaction needed |
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:
