debug.log filling up with message about cache invalidation

[iowebgr]

Hi, I'm experiencing a serious issue with debug.log filling up with messages from  cache_invalidate like this

https://pastebin.com/Q477F7jU

It's getting to the point where the messages can fill the entire disk within a single day but I'm not sure why this is happening. The site is locked by basic authentication so there's virtually no traffic.

Yet this message keeps spamming.

I'm not sure what may be causing it, any ideas?

I'm on Magento 2.4.1

I ended up

- disabling cron

- truncating all index tables,

- reindexing the site manually

and flushing all caches.

This seems to have stopped the cache flush spam but I wonder what's the root cause for this issue.
