Getting the following errors in my mongos log upon attempting to query a sharded collection.
ns: database.coll could not initialize cursor across all shards because : stale config detected for ns: database.coll ParallelCursor::_init @ rs_a/hostA:27018,hostB:27018 attempt: 0
The error is originating from an application server running mongos which loads its config from three distributed config servers. The mongo cluster itself has two shards each with a three member replica set. The error is accompanied by severely degraded performance.
Running Mongo 2.0.1 and using the java driver.
