I believe this is due to the EIT requesting large numbers (~30 at a time for me) of complete reschedules in a short time. The simplest solution is to comment out the call "ScheduledRecording::signalChange(-1);" in eithelper.cpp ~line 123 This does mean that schedule changes are not picked up immediately, but schedule changes are picked up fairly regularly anyway by normal use.
