The issue is onphp-fpm container and the error logged is:

In Container.php line 147:
Circular reference detected for service "token", path: "token -> cache_tags
.invalidator -> plugin.manager.block -> logger.channel.default -> logger.fa
ctory -> logger.filelog".

Let's use this issue for investigation purposes and follow-up on these websites.
