Thanks for the output.

At least for mprofile enospc error, the problem itself is very 
straightforward, just unable to alloc tree block.

I'll check the codes to see if we can improve it, by finding out why we 
can't alloc a new chunk to resolve the problem.

But I'm still a little concerned about the dprofile case, as this time, 
dprofile doesn't trigger a ENOSPC and my debug info is not triggered.

Thanks,
Qu
