    Description

      The memory usage of MaxScale keeps growing and eventually swap is used and then MaxScale gets busted one night (or day).

      Issue observed on our pre-prod MaxScale - version 23.02.1. The same observed in prod (6.2.1). Currently, holding prod upgrade.

      Stack trace has been logged (attached). Next step is using jemalloc to profile the heap as Markus suggested.
