We had four query servers, but then decided it was overkill. We shutdown two of them and now we are seeing empty result from n1ql intermittently. When I query the same n1ql directly on cbq, I get the result. For the last 10 hours, we’ve seen 5 queries that returned an empty result. It’s not a huge deal as it rarely happens, but we would like to know what’s causing it. Is there a way to debug it?
We are using PHP SDK with 4.1 EE version. We already restarted all the PHP servers just in case. It did not help.
