I occasionally get an assertion error when running mongos with sharding. I've got a mini-cluster with 3 nodes running, where each node has a mongod instance and a mongos instance running. One of the machines also has an additional mongod instance running, acting as the config server. The setup is basically the same as described on the "Sample Configuration Session" wiki page (i.e. i have a "test.people" collection, which uses the "name" as the shard key). I've inserted about a million rows in the collection, resulting in 123 shard chunks. To load test, I've set up each of the nodes to run a bunch of simple queries against their "localhost" mongos instances. The queries are of the form {name:{$gte:"foo",$lt:"bar"}}. Things work great about 90% of the time, but sometimes I get this error in the mongos logs: Wed Sep 23 18:46:41 connection accepted from 10.244.254.3:34215 #6 On the client side, the error shows up as: java.lang.RuntimeException: db error [] Any ideas? |
