Symptoms

On 11.5.9 in Test:
Users run an MRP plan in test after adding an organization and other data to the plan. However
when they run the plan only the Snapshot Monitor (MRCMON) and Memory Based Snapshot (MRCNSP) show running and everything is in Pending Standby. The logs show the following

Snapshot Monitor log file:

In timeout
Message type:6 File type:1
fetching info on request: 15478
fetching info on request: 15481
In timeout
Message type:6 File type:1
fetching info on request: 15478
fetching info on request: 15481
In timeout
(This repeats indefinitely.)

Memory-Based Snapshot log file:

Flushed all buffers into MRP_SYSTEM_ITEMS
Message from Monitor: 2
Message from Monitor: 2
Message from Monitor: 2
Message from Monitor: 2
(This also repeats indefinitely.)

Expect MRP plan to run and concurrent processes to be launched and run successfully

STEPS
The issue can be reproduced at will with the following steps:
1. Add new organization and data for a new MRP plan run
2. Launch MRP plan
3. MRCMON and MRCNSP hang indefinitely
