Jianxia Chen commented on GEODE-493:
------------------------------------
Similar to GEODE-699, it is due to thread scheduling for fetch task in
ClientMetaService, although the test has been waiting for 60 seconds for all
threads to complete. Note that there are 312 PUTs in the test, each of these
PUTs can potentially spawn a fetch task thread. And if there is GC involved,
completion of these thread can be further delayed.
