Just one nextcloud.log entry over 8,000,000 characters!

Nextcloud 20.0.4, PHP 7.4, Ubuntu 18.04LTS

I have a problem with my Nextcloud. It works, but ends up consuming system resources with huge log entries.
The first thing I did was disable xdebug entirely (plus xdebug.max_nesting_level =1024 had been set) - so I dont think this is an xdebug issue.
If I open just one logfile entry in Notepad++, it is 8,308,704 characters long. The log rotates with 5 or 6 entries!
What else could be causing this?

kessellb, thanks for the reply - I don’t think this is limited to mail or ,ail app related issues. I get a similar entry with LDAP and other functions.

It is like the log file itself is looping into itself, however as I said I think I have ruled out xdebug - so what else could result in reaching “Maximum function nesting level of ‘256’ reached, aborting!”,
