Incorrect usage of Timer can cause thread blocking

[NeJan2020]

Describe the bug

kindling/collector/pkg/component/analyzer/cpuanalyzer/send_trigger.go

Lines 163 to 166 in d4e8e64

	if !s.timer.Stop() {
	<-s.timer.C
	}
	s.timer.Reset(s.expiredDuration)

Since this timer is listened on by multiple routines, trying to accept the remaining signals in the Timer.C after calling timer.Stop() may cause thread blocking.
