---------------------------------
Summary: In JvmPauseMonitor, sleepTime should not be larger than
sleepDeviationThreshold
Key: RATIS-1877
URL: https://issues.apache.org/jira/browse/RATIS-1877
Project: Ratis
Issue Type: Bug
Components: util
Reporter: Tsz-wo Sze
Assignee: Tsz-wo Sze
Current the JvmPauseMonitor.SLEEP_TIME is hard coded to 500ms and the default
value of sleepDeviationThreshold is 300ms. In this case, JvmPauseMonitor may
not be able to detect an extra sleep violating the threshold. Consider the
following:
# JvmPauseMonitor sleeps at T
# A pause start at T+50ms and ends as T+400ms, i.e. the pause is 350ms
# JvmPauseMonitor wakes up at T+500MS and detects no extra sleep.
