The server I rent at Multiplay is suffering profound instability, crashes and memory issues. Crashes constantly with same value: 3221225477

Registered performance parameter history graph:

What you see here:

1. First start since update. Server suffers huge memory leak allocating 3.6 GB (2x normal) with no players.
2. Performance is unstable. At 17:20 mark the server suffers a performance crash and freezes.
3. Second start is right-most section of graph. Server suffers rapid restarts(indicated by memory reallocations).
4. Performance is highly unstable and rarely reaches more than 10% of normal performance.

Note that in both instances, start-up performance is <10%.
