PHP Error Log filled due problem with max_allowed_packet

Below an example of an ‘endless’ PHP Error Log File (Size 2TB!!!). It is partially german, but I think it is clear that update in table option creates an endless and rapidly growing (over 50MB/Min.!!!) PHP Error Log due to “Got a packet bigger than ‘max_allowed_packet’ bytes” problem.

Any idea how to stop it beyond disabling or limiting PHP Error Log?

Version info:
WordPress Version: 4.9.8.
PHP Version: 7.2
MySQL Version: 5.5
Remove Google Fonts References Version: 2.6

PHP Error Log Example:
