Werk #398: Tolerate debug output in check plugins when using CMC

Component Core & Setup
Title Tolerate debug output in check plugins when using CMC
Date Dec 18, 2013

Checkmk Version 1.2.5i1
Level Trivial Change
Class Bug Fix
Compatibility Compatible - no manual interaction needed

When using the Check_MK Micro Core and at the same time check plugins output debug information to stdout, the communication with the core was garbled up and the check helper died with an exception. This fix eliminates any unauthorized output to stdout be removing the filedescriptor to a save place and replacing stdout with /dev/null.
