100% CPU load

Open hdid opened this issue 6 years ago • 4 comments

Sometimes after heavy loads; one of child processes continues 100% loading and does not come back to normal load! (even if i'm not using it).

I confirm this issue. What could be workaround for this unpleasant behavior of such abnormal tasks?

My temporary dirty solution is to add next 2 lines in systemd unit:

Restart=always
RuntimeMaxSec=600

Could you get some backtraces to figure out what's going on? This might help:

I also have seen high CPU usage but in my case it was external clients who discovered my open proxy and were routing through it. This is why I added HTTP BASIC authentication in #20.

@gaul, absolutely only I use my proxy: access to it is available only for local addresses. I can reproduce a case of this bad behavior:

  1. open a large image in a separate browser tab (3-5 MB);
  2. close this tab without waiting for a full download. After that, the cpu is loaded 100% until you kill the process.
