Hi, I was wondering if anyone can help me picture what sort of scenario could result in hour-long recursion times. For example, [1224870602] unbound[22560:0] info: server stats for thread 0: 1376 queries, 108 answers from cache, 1268 recursions [1224870602] unbound[22560:0] info: server stats for thread 0: requestlist max 55 avg 23.2926 exceeded 0 [1224870602] unbound[22560:0] info: average recursion processing time 58.964890 sec [1224870602] unbound[22560:0] info: histogram of recursion processing times [1224870602] unbound[22560:0] info: [25%]=0.0458265 median[50%]=0.116073 [75%]=0.237329 [1224870602] unbound[22560:0] info: lower(secs) upper(secs) recursions [1224870602] unbound[22560:0] info: 0.000000 0.000001 79 [1224870602] unbound[22560:0] info: 0.004096 0.008192 2 [1224870602] unbound[22560:0] info: 0.016384 0.032768 56 [1224870602] unbound[22560:0] info: 0.032768 0.065536 34 [1224870602] unbound[22560:0] info: 0.065536 0.131072 202 [1224870602] unbound[22560:0] info: 0.131072 0.262144 284 [1224870602] unbound[22560:0] info: 0.262144 0.524288 309 [1224870602] unbound[22560:0] info: 0.524288 1.000000 69 [1224870602] unbound[22560:0] info: 1.000000 2.000000 17 [1224870602] unbound[22560:0] info: 2.000000 4.000000 7 [1224870602] unbound[22560:0] info: 4.000000 8.000000 7 [1224870602] unbound[22560:0] info: 8.000000 16.000000 5 [1224870602] unbound[22560:0] info: 16.000000 32.000000 7 [1224870602] unbound[22560:0] info: 32.000000 64.000000 8 [1224870602] unbound[22560:0] info: 64.000000 128.000000 64 [1224870602] unbound[22560:0] info: 128.000000 256.000000 53 [1224870602] unbound[22560:0] info: 256.000000 512.000000 9 [1224870602] unbound[22560:0] info: 512.000000 1024.000000 16 [1224870602] unbound[22560:0] info: 1024.000000 2048.000000 14 [1224870602] unbound[22560:0] info: 2048.000000 4096.000000 7 As you can see by the last few lines, some queries are taking a *long* time. I run unbound on several low-traffic resolvers, all of them configured the same, but I see times greater than 256 secs only on one of them. I'm having trouble imagining how a query could last an hour. Just trying to get a big-picture idea of what might be going on. Any thoughts?
