TYPO3 Core

I have regular error messages in the logs due to Dependency Injection cache /var/cache/code/di. This improved considerably, after switching from shared (NFS) to the VM storage, but has not disappeared.

This also results in error message when loading a page in frontend. When page is loaded again, it is ok. Since (page) cache is warmed up at night and after deployment, these errors are usually not noticed, but it does happen.

Switching to non-NFS:¶

- entire var/cache/code switched to local storage
- when deploying, system cache on all machines must be flushed (and opcache also, of course)
- cache is warmed up during deployment ("@php vendor/bin/typo3 cache:warmup")

The number of log messages with these errors are reduced. Last time I checked, I had roughly 60, all with nearly same timestamp (within 20 seconds).

setup¶

• TYPO3 11.5.24
• dual machines behind load-balancer, however currently only one at a time utilized, other is fallback
• uses the defaults for caching, except what is usually in the DB is in Redis and b13/distributed-locking is used for shared locking. var/cache/di is switched to local storage
