My response mainly focused on the "real" problem that the caching server (occasionally?) returns SERVFAIL for that specific query. Are you saying the server is still returning SERVFAIL even after raising max-cache-size and even if the server does not reach that limit? To answer the question directly...we need more information. What specifically did you try and which "this information" exactly are you talking about? Does that happen with mostly empty cache? Is it reproduceable or occasional? It would be helpful if you can show detailed steps toward the question, like - starting a server - dig the server with a query - do rndc dumpdb and show the dump output, explaining which information you're expecting in the cache but isn't there. Note that there's nothing wrong about some information not in a cache per se (entries can be purged for various reasons, by default). So you should first explain that it should be in the cache according to the detailed procedure. It should also be noted that missing cache itself is not necessarily problematic as long as the required information is finally returned (though suboptimal in that it may take longer time and consume more resources). So it's also helpful to explain whether it causes a real problem like SERVFAIL. --- JINMEI, Tatuya Internet Systems Consortium, Inc.
