MongoDB "Couldn't Send Query"
Hold on Cowboy
This blog post is pretty old. Be careful with the information you find in here. It's likely dead, dying, or wildly inaccurate.
I would get random error messages from my MongoDB based app GoScouter of
couldn't send query
It was random and quite frustration. I was not able to find anything definite online about such error, but that it might be a bug in the PHP MongoDB Driver. I was using version 1.2.7, so I did a pecl upgrade mongo
on the web server (using PHP-FPM) and this seemed to fix the problem. Now I’m running version 1.2.9 and I have not received a Couldn't Send Query
error yet.
