ID: 3286 Title: Fixing possible logging issues when using datasource programs for monitoring Component: Core & Setup Level: 1 Class: Bug Fix Version: 1.2.9i1 When calling datasource programs for monitoring they are executed as subprocesses of Check_MK. Check_MK as passing all filedescriptors except stdout and stderr to the subprocess. So if a subprocess was doing something strange with them it could happen that this influenced the handling within Check_MK. This could, for example, confuse the communication between the CMC and the Check_MK keepalive helper processes.
