[2.4.0] Checkmk Werk 16813 created: Changed aborting behavior for overrunning cached agent plugins

[//]: # (werk v2) # Changed aborting behavior for overrunning cached agent plugins key | value ---------- | --- date | 2024-05-03T09:42:12+00:00 version | 2.4.0b1 class | fix edition | cre component | checks level | 1 compatible | yes This Werk changes the exact condition under which the Unix agents kill long running cached agent plugins. Affected are the Checkmk agent plugins for Linux, AIX, Solaris, OpenWrt and FreeBSD. ### Previous behavior Any agent plugin that ran for more that twice its caching interval _without generating output_ was killed by the agent. The agent checked for this every minute. ### New behavior Any agent plugin running for more than twice its caching interval will be killed. It is no longer relevant wether the plugin produces output during that time. The killing is done from within the asynchronous process itself, eliminating any potential danger of inadvertently killing the wrong process.
