Other is part of the safepoint, but the time is not included in the "gc,cpu" end time block. [2022-10-09T13:16:39.707+0000][3783.195s][debug][gc,heap ] GC(9) Heap before GC invocations=9 (full 0): garbage-first heap total...
Track G1 external root scanning time for analysis. For example: https://access.redhat.com/solutions/6976511
There were more that 1000, mostly 'debug', but also 'info' level. `[2024-02-01T11:09:50.737+0000][0.011s][debug][gc ] ConcGCThreads: 3 offset 29 [2024-02-01T11:09:50.737+0000][0.011s][debug][gc ] ParallelGCThreads: 13 [2024-02-01T11:09:50.737+0000][0.011s][debug][gc ] Initialize mark stack with 4096 chunks, maximum...
