Hi Jan, Looks like you're running out of memory and having high GC load. Indexes and query execution requires some additional memory, you should take this into account when planning capacity. Can you try to allocate more heap memory and check if it helps? I would also recommend to use JVM settings provided in [1], there are proven to be effective in majority of use cases.
