Are you setting the keepAlive and keepAliveInitialDelay options? Because Mongoose doesn't set those.

The MongoDB Node driver is deprecating those options. The recommended approach is to remove those options, because keepAlive defaults to true in Mongoose >= 5.2.0 anyway.

We can close this, we were using this only on tests, it was helping with timeouts on tests

Should we just remove or is there some replacement?

[vkarpov15]

Just remove it. keepAlive: true does nothing since keepAlive is true by default, and there isn't really much need to set keepAliveInitialDelay. We had that option in the connection docs just as a copy/paste.

If you have problems with timeouts in your tests after removing these options, please post a note here and we'll help you debug.
