Hello, it is recommended to upgrade to latest 4.2.x -- there were some fixes since version 4.2.1. The same configuration file and database structure works for all 4.2.x, therefore just deploy the newer 4.2.x like you did with 4.2.1 and just restart.
After upgrade, if you still see decrease of pkg free memory, let us know to investigate further.
