Random issue with cache/restore

[cdupuis]

Starting this morning we are experiencing random failures to restore caches successfully. Nothing has changed in our setup and the cache exists. Other builds in the same matrix can successfully restore the same cache.

We see the following logs:

Run actions/cache/restore@d4323d4df104b026a6aa633fdb11d772146be0bf
Cache hit for: clamav-db
Warning: Failed to restore: 
Cache not found for input keys: clamav-db

We also have problems with

Run actions/cache@v4

In addition to the above, we also see that caches randomly appear and disappear when loading the cache page.

We've also been experiencing the same issue. A cache key had been found, but restoring cache failed.

Same here and same for caches: for some trying to deleting it, getting errors and on page reload sometimes no cache shown, sometimes some new entries pop up

It seems that not a recent code change cause this issue.
Is it related to the cache action service side issue?
