|Title||Fixed slow activation of changes due to loss of IP address cache|
|Checkmk Edition||Checkmk Raw Edition (CRE)|
|Compatibility||Compatible - no manual interaction needed|
In some situations Check_MK would loose the cached IP addresses in var/check_mk/ipaddresses.cache. The results in the next activation of changes being very slow - depending on your DNS. The problem seems to happen (especially) if you have activated periodic service discovery with automatic activation of changes.
This has been fixed.
