Hi there! I'm using mongodb 2.0.5 with java driver 2.7.3 Current configuration is two shards with three replicas each Mongos is deployed locally.
When I run long query in Java (full scan on 3000000 documents, 2-3 kilobytes each) after about an hour the process fails with the exception [2012-07-18 17:49:06,787] ERROR [main] { "$err" : "getMore: cursor didn't exist on server, possible restart or timeout?" , "code" : 13127} No hardweight ops performed inside iterating loop.
Here is mongos logs: Wed Jul 18 17:49:05 [conn4] want cursor : 4809402721582786738 Wed Jul 18 17:49:05 [conn4] CursorCache::get id: 4809402721582786738 Wed Jul 18 17:49:06 [conn4] hasMore: 1 sendMore: 1 cursorMore: 1 ntoreturn: 0 num: 526 wouldSendMoreIfHad: 1 id:4809402721582786738 totalSent: 1684483 Wed Jul 18 17:49:06 [conn4] Request::process ns: testdb.load msg id:2986 attempt: 0 Wed Jul 18 17:49:06 [conn4] want cursor : 4809402721582786738 Wed Jul 18 17:49:06 [conn4] CursorCache::get id: 4809402721582786738 Wed Jul 18 17:49:06 [conn4] creating new connection to:mongodb02:27017 Wed Jul 18 17:49:06 BackgroundJob starting: ConnectBG Wed Jul 18 17:49:06 [conn4] connected connection!

update: On production environment this process fails in 5 minutes, number of processed rows seems to be the same. So, obsolete cursor is definitely not a reason.
Any ideas?
