Rails mongodb carrierwave gridfs 的问题

smallbug · 2013年01月08日 · 2423 次阅读

昨天我在研究mongodb carrierwave gridfs的时候,发现我上传20M的文件的时候运行正常,当我上传一个40多M的文件的时候就报错。 Could not connect to a primary node for replica set <:cluster nodes="[<Moped::Node" resolved_address="">]> 有时候会是内存溢出的错误 然后不知道是什么问题,我看到Mongodb.log文件里面的报错是 Tue Jan 8 16:15:13 [conn600] recv(): message len 49804658 is too large49804658
