The specified update command has been issued with either an invalid combination of MONTH and DAYOFMONTH, or a specified MONTH or DAYOFMONTH value is incompatible with a MONTH or DAYOFMONTH value that is not being updated for the existing schedule. If there is just one month and one day combination and that combination is invalid, the command will fail. If there is at least one valid month and day combination, the schedule will be updated and run on the valid dates. The schedule will skip the invalid month and day combinations.
Server operation continues.
To see the options for the existing schedule, issue "q sched f=d" for the client or administrative schedule. Determine the correct day and month combinations. If the the command failed, issue the update command again.
