ID: 3737 Title: Fixed slow activation of changes due to loss of IP address cache Component: Core & Setup Level: 2 Class: Bug Fix Version: 1.4.0i1 In some situations Check_MK would loose the cached IP addresses in <tt>var/check_mk/ipaddresses.cache</tt>. 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.
