Hello,
Since updating wapt + debian following the wiki procedure, my python process is always at 99.9%:
771 wapt 20 0 198608 83228 13776 R 99,9 4,1 5:20.27 python
I restart the service, it works fine for 30s then it goes into a loop.
By running `strace -f -p pid`, we see that at the moment the CPU goes haywire, there's an avalanche of calls in an infinite loop:
(3, [],
0
1023
epoll_wait
)
`
=
0`
,1023, 0) = 0
epoll_wait(3, [], 1023, 0) = 0
epoll_wait(3, [], 1023, 0) = 0
epoll_wait(3, [], 1023, 0) = 0
I am running on an ESX, I tried changing the type of network card: switching to e1000 but it didn't change anything.
Best regards

Hello,
we have just identified the problem.
We have upgraded some libraries to the latest version. However, one of the libraries is causing an issue.
A fix for the library has just been released:
https://github.com/miguelgrinberg/pytho ... CHANGES.md
Prevent heavy CPU usage when decoding payloads:

We will be releasing a new version of wapt today.
