MongoDB C++ auto reconnect

[Carl Z.]

Hello!

I've been facing a problem with auto reconnect. I've set it to true but whenever I restart MongoDB my c++ app crashes with error:

Thu Mar 21 12:02:55.245 DBClientCursor::init call() failed

exception: DBClientBase::findN: transport error: 127.0.0.1:27017 ns: ..... query .......

I could just try-catch all query but that would be kinda insane, so... is there an easier solution for this?

If you look at the code you will see that there are situations where an exception is thrown even when autoReconnect is set.

Can you check the server logs and see what is actually going on that is causing the connections to fail?

Sadly there is nothing in the logs.

Also if I catch the exception at the first query on the next one it reconnects to mongo. That doesn't really help though since I don't know when will mongo crash (or a simple restart, anything), so I still have to catch exception at every query.
