Rolling Restart of NBA server nodes on every 15 days/Once in the month for Application maintenance activities.

As a best practices and avoid following issues, we need to reboot all NBA server nodes one by one on every 15 days/ Once in the month for Application maintenance activities.. Could you please provide your view on this. Thanks!

Marketing and decision agents will be stuck
System Pulse will be always high
Lot of latency issues in NBA

Wrong rule running and erratic system pulse, for example
System pulse is suspected of not keeping rules synchronized across nodes.
Pulse fails to pick up or apply a rule change on one or more nodes.
Rule resolution or rule cache issues appear in a multi-node deployment or on a single node (unknown causes related to system pulse).
Hung threads
Thread dumps that can cause system performance issues
Out of memory errors
Static content errors
Failure to regenerate a Rule-Utility-Function (RUF) or Rule-Utility-Library (RUL) after a RAP import
