In my experience, 4s pause for a 160gb heap is rather unusual and
unexpected particularly on a young-only collection. Even on jdk8 (later
jvms are much better), but it certainly depends on application.
saw that pause time before? I think it's pretty hard to tell after the
fact, but with such a large system I would lean towards problems outside
of the JVM.
According to https://access.redhat.com/solutions/46111 you can get
statistics about THP activity looking at /proc/<pid>/vmstat.
This looks just like one of these one-off occurrences THP could cause.
Thanks,
Thomas
