I embedded YAWS in my application at production environment, and I found the yaws_log message count is continue growing (from 08/Dec/2016 ). messages

Observer shows the yaws_log process Memory size is 2326160312, and the Message count is 799501 observer

The localhost:8081.access file size is 2.5Mb and the last log time is 08/Dec/2016:11:14:26, but today is 12/Dec/2016.

I also check the disk, but it is not full.

Update

I'm using YAWS 2.0.4 and Erlang/OTP 19.1

Below are partial messages in the yaws_log process

Pid = whereis(yaws_log).
erlang:process_info(Pid, messages).

  • Please provide the versions of Yaws and Erlang/OTP you're using. – Steve Vinoski Dec 12 '16 at 14:57
  • Also, please double-click the `yaws_log` process and in the new window choose the Messages tab. What do the messages in the queue look like? – Steve Vinoski Dec 12 '16 at 15:39
  • Please also provide the output of `process_info(whereis(yaws_log)).` – Steve Vinoski Dec 13 '16 at 14:16
  • The message of yaws_log is growing to 1 million, and the service become unstable. So I restarted the server yesterday. I will continue watching the yaws_log process, and remember to execute `process_info(whereis(yaws_log))` , thank you. – chengweichao Dec 14 '16 at 02:04
