1 Title: Gracefully restart check_mk helpers in case of memory leak
8 When using the Check_MK Micro Core in combination with inline SNMP then
9 in certain rare situations the check_mk helper processes leak memory. We
10 suspect the leak to be in the SNMP libs but this is just an assumption.
12 This fix now watches the size of each check_mk helper. If the memory usage
13 (VM size) of the process grows by more then 50% compared to the size after
14 the first 20 hosts being checked, then the helper silently restarts itself
15 and leaves a message in <tt>var/log/check_mk/cmc-helper.log</tt>.
