I never seen or had this before. But 132 cache entries seem not much. But use up all 2mib of cache? These “cache full” messages I see for several hours now. So it seems the cache entries do not expire or free.
[foo@bar] /ip/dns/cache/all> print count-only
133
Anyone a clue?
Another finding:
After a
/ip/dns/cache/flush
there are only 12 cache items left:
/ip/dns/cache/all/print count-only
12
But the cache is still utilized to the full 2048kib.
cache-size: 2048KiB
cache-used: 2048KiB
And I still get the “cache full” errors.
Holy chick.

What’s wrong? This cna’t be a bug known and reported months ago.
