I haven't dug into the relevant OSD code in a while, but I think it's a lot more likely your OSD is just overloaded and is taking a while to send a lot of different messages, and that the loop it's in doesn't update the HeartbeatMap or something. Did you check that?
Thank you for your continuous helpJ.
We are using hammer 0.94.5 version, and what I read is the version of the source code.
However, on the other hand, if Pipe::do_recv do act as blocked, is it reasonable for the Pipe::reader_thread to block threads calling SimpleMessenger::submit_
message by holding Connection::lock?
I think maybe a different mutex should be used in Pipe::read_message rather than Connection::lock.
I don't think it does use that lock. Pipe::read_message() is generally called while the pipe_lock is held, but not Connection::lock. (They are separate.)
