Rapid 404/301 access.log errors when LSCache for WordPress is enabled

[ronaldst]

I run OpenLiteSpeed 1.6.17 on CentOS 7 + LSPHP 7.4.

I recently noticed that enabling the LiteSpeed Cache -plugin on my WordPress site is cusing a very high load on the server. Further investigations I find a rapid growing access.log with these types of errors:

Disabling OpenLiteSpeed Cache returns everything to normal, which is good but obviously not optimal. I would like to run the LSCache plugin.

Would anyone be able to shed some light on what is the problem here?

Thank you.
