Hi all:
Question about Last ditch collection.
I used JDK 8 , find out info about Last ditch collection from gc log.
Cause CountAvg Time Max Time Total Time
Time %
Last ditch collection 8420 min 46 sec 593 ms1 hr 6 min 17 sec29 hrs 5
min 13 sec49.27%
Metadata GC Threshold 10216 min 58 sec 215 ms59 min 70 ms 28 hrs

Have question:
How to get root cause？ Metaspace fragment ?
The log should contain information about whether the last ditch
collections collections are caused by a full java heap (i.e. heap memory
usage) or not.
I think the "Metadata GC threshold" collections also contain metadata
usage information.
Thanks,
Thomas
