Function sentinelCheckTiltCondition

app/redis-6.2.6/src/sentinel.c:5086–5096

This function checks if we need to enter the TITL mode. * * The TILT mode is entered if we detect that between two invocations of the * timer interrupt, a negative amount of time, or too much time has passed. * Note that we expect that more or less just 100 milliseconds will pass * if everything is fine. However we'll see a negative number or a * difference bigger than SENTINEL_TILT_TRIGGER

 *
 * During TILT time we still collect information, we just do not act. */
