| Description |
|
We're commonly running into this warning in environments we feel are properly configured. It's a warning, not an error, but it's still creating friction through confusion among the user base, so it would be nice to address.
The issue is that WiredTiger now uses a file descriptor per namespace, meaning the number of file descriptors required can quickly outstrip the number of connections used in heavily multi-tenanted environments (commonly development and test) where connection requirements are modest but namespaces abound.
