I'm not convinced this is the right approach, why is the statement getting closed? it's not a network connection so shouldn't suffer from network problems. This seems like it's masking a real problem.

@rvagg I see what you mean. Have reverted this change.

@rvagg Do you mean to say that there should never be a transient conn error with Sqllite ? |
|
I can't imagine why. Unless the docs suggest otherwise? It's basically an open file descriptor? |

@rvagg I see what you mean. I have reverted that change. I have a strong suspicion based on meandering through the code that the RPC context cancellation from the client side (say a transient RPC connection failure) while a statement is executing is causing this. I've added some logging to look this up the next time we run into this. |
