Hey, I ran into this problem too! I solved it by re-defining the check
to use flock so that the checks wait for each other to finish instead
of running concurrently:
object CheckCommand "dhcp-lock" {
import "dhcp"
command = [ "/usr/bin/flock", "-w", "15",
"/run/icinga2/check_dhcp.lock" ] + command
}
