| ERROR | unable to determine valid execution date from repeat interval |
| CAUSE | The specified repeat interval contained conflicting clauses that made it impossible to ever find a matching date, e.g., FREQ=YEARLY;BYMONTH=FEB;BYMONTHDAY=31. Alternatively, the scheduler reached its maximum number of attempts to try to find a valid execution date. This occurs when theoretically there is a valid execution date far in the future, but the scheduler took too many attempts to determine this date. |
| ACTION | Remove the conflicting clauses, or simplify the repeat interval so that it is easier to determine the next execution date. |
