Description
My application is write intensive. The op type is only insert. During the begin hours every thing is ok, but after that the insert op may takes a very very long time. I have no idea of why that happen. The log:

currentOp show that one insert operation is processing while others are waiting for lock.
The data size is about 12G. The index data is small against RAM.
After restart(I must kill mongod process) it will run normally hours again, but hang again at last.
