我使用MongoDB 3.0.3和C＃驱动程序1.10.0.62
我有2个分片并设置writeConcern: W = 2, WTimeout = 5000
当我使用方法col.Insert(data, writeConcern)时，程序总是抛出异常，如下所示：
MongoDB.Driver.MongoWriteConcernException: WriteConcern detected an error 'waiting for replication timed out at shard01'. (Response was { "ok" : 1, "code" : 64, "err" : "waiting for replication timed out at shard01", "n" : NumberLong(0) }).
这些例外经常发生。有谁知道如何处理它们？
