Symptoms

On : 12.1.3.8 version, Memory Based Planner

We are experiencing an issue when running MBP. Twice this morning, the MSONWL64.EXE Is Consuming All Memory On System and the servers fail.
We have seen it consuming 100% capacity and 83G out of 146G total Memory. Users are on 12.1.3.8 which they just applied

MSONWL64 module: Memory Based Planner 64-bit Linux

DIR: /ascsbx/app/applmgr/IRASCSBX/inst/apps/IRASCSBX_igrexanwh002cn04/logs/appl/conc/out/data26/

Right after a calendar section of the log I see a bunch of messages with 22066 error:

SELECT TO_CHAR(period_start_date, 'j')
FROM msc_period_start_dates
WHERE calendar_code = :calendar_code
AND sr_instance_id = :instance_id
AND to_number(to_char(period_start_date, 'j')) >=
  to_number(to_char(sysdate, 'J')) - 365
AND exception_set_id = :exception_set_id
 ORDER BY period_start_date

  0:00
APP-MRP-22066: check_bounds: Invalid value of '-1' for the argument 'index'

Cause: The current routine was passed an invalid value for the specified argument.

Action: Contact your customer support representative.

Then after a bunch of the above the log continues on. Then the same error message starts printing again. This repeats many time and then finally we see the following at the end of the log:

Solve LP t = 771 seconds.
