Some time, low frequency, some of the bucket has been locked, I got nothing valuable information from jstack and log, after some effort, i just know a bucket has been locked, and many thread waiting for this lock, but I don't know which thread locked this lock, and how about the state of that thread now. Eventually, i give up, and restart the OM, anything goes well as normal.
