Comment (by lucylangthorne55@…):

 Looking at the code a bit more I noticed that the first schedule (which
 will be a slower full schedule) is excluded from the max schedRunTime,
 hence schedRunTime is typically for fast "schedule single item" queries.

 But I think that when a slave connects, the master does a full reschedule
 (which is time consuming) and this is included in the schedRunTime max.
 Once that maximum is set, it is used for all future loops.

 This could explain why this issue occurs more frequently when run with a
 slave.
