1. The log has 47 GC operations over a 36-minute interval from 7:00 AM to 7:36 AM on 30th March 2023 UTC. 
2. The GC operations start at roughly one per minute and take less than five seconds each, but after 7:23 AM, they abruptly take about 30 seconds each and occur twice a minute. In other words, initially, GC operations take up a small fraction of the JVM time, while later, they take up almost all of its time.
3. GC operations in this second period result in a very slight decrease in the total memory size and the PSYoungGen, ParOldGen, and Metaspace memory areas. This behavior is especially acute after 7:26:51 AM.
4. This indicates much time spent in GC operations with little result.
5. The total memory size initially slowly grows from 49.5GB to 52.3 GB, but in the second period maxes out at around 78 GB. 
6. The allocated memory size is fixed at 82 GB during the second period of GC operations, indicating an outer limit.
7. I recommend increasing the maximum allocated memory beyond the 82 GB limit, doubling it if possible, and re-running the JVM.
