Check_MK Werk 1045: Gracefully restart check_mk helpers in case of memory leak

ID: 1045 Title: Gracefully restart check_mk helpers in case of memory leak Component: Core & Setup Level: 2 Class: Bug Fix Version: 1.2.5i5 When using the Check_MK Micro Core in combination with inline SNMP then in certain rare situations the check_mk helper processes leak memory. We suspect the leak to be in the SNMP libs but this is just an assumption. This fix now watches the size of each check_mk helper. If the memory usage (VM size) of the process grows by more then 50% compared to the size after the first 20 hosts being checked, then the helper silently restarts itself and leaves a message in <tt>var/log/check_mk/cmc-helper.log</tt>.
