Reduce Memory Usage of MongoDB

If MongoDB is using too much memory and fails, reduce its cache size:

1. On the DPF server, open the configuration file of MongoDB in an editor:

   C:\ProgramData\SEAL Systems\config\mongod.conf
   

2. Add the following lines to storage to reduce the cache size. Adapt the value as needed.

       wiredTiger:
           engineConfig:
               cacheSizeGB: 2
   

   Example of mongod.conf

   storage:
       dbPath: /opt/seal/data/seal-mongodb
       wiredTiger:
           engineConfig:
               cacheSizeGB: 2
