Subject: a problem of long STW because of GC ref-proc

Seems your block size is very small (16KB), so there will be
70*1024*1024/16=4587520 block (at most) in your BucketCache.
For each block, the RS will maintain a soft reference idLock and a
BucketEntry in its bucket cache.  So maybe you can try to
enlarge the block size ?
