WebOne constantly consumes CPU on my server

[bodqhrohro]

I experienced it sporadically for several months already: at some point, it caused high CPU load (and possibly I/O too?), causing LA>100 and making the VPS almost unresponsible, as well as the rest of services on it. It relieved with a restart though.

Today it constantly causes a high load, even right after a restart. I tried:

• upgrading from 0.15.3 to 0.17.0

[WebVideoOptions]
Enable=no

• commenting all the authentication strings out, for the case something is abusing it

Nothing helped. I also looked into /var/log/webone.log, the failed authentications are quite rare there, several per an hour.

How do I delve into the cause more deeply?

Very strange and very interesting bug. The only that I know about debugging options is to run under some debugger (may be Visual Studio Code, but not tested - I've using Visual Studio Community Edition which is not available for Linux) and pause running at the time when CPU load became too high, then find current execution points for each thread.

And I have not seen such behavior when tested on my VPSes.

Seems like one of the reasons is exceeded disk space. Hope you can reproduce this case at least.

I am not able to reproduce this.

Does this problem appears with 0.17.2? I've fixed similar bug in it.
