In case a helper detects that it has new open file descriptors after performing checks, it writes lines like these to the cmc.log:
2016-10-25 16:15:59 [4] [Check_MK helper 11344] >> Open file descriptors changed after %d cycles. Currently open: 2016-10-25 16:15:59 [4] [Check_MK helper 11344] >> 0 -> socket:[1030046] 2016-10-25 16:15:59 [4] [Check_MK helper 11344] >> 1 -> pipe:[1030047] 2016-10-25 16:15:59 [4] [Check_MK helper 11344] >> 2 -> pipe:[1030047] 2016-10-25 16:15:59 [4] [Check_MK helper 11344] >> 3 -> socket:[1030046] 2016-10-25 16:15:59 [4] [Check_MK helper 11344] >> 4 -> /tmp/x 2016-10-25 16:15:59 [4] [Check_MK helper 11344] >> 5 -> UNKNOWN 2016-10-25 16:15:59 [4] [Check_MK helper 11344] >> 6 -> /dev/urandom
This may help detect and debug file descriptor leaks.
