Hello,

I’ve just updated my docker webtunnel bridge.

But since I did, the WTB consumes one CPU core all the time, despite working fine.

I always had this problem when starting the bridge, but it would go away after a few minutes. Now it stays at 100% for hours.  
What can I do ?

Hi Maledict

You’re not alone there are multiple people with the same issue. I’ve created an issue on gitlab [100% CPU usage on webtunnel bridges since 0.4.8.20 (#41172) · Issues · The Tor Project / Core / Tor · GitLab](https://gitlab.torproject.org/tpo/core/tor/-/issues/41172)
