At around the same time as https://jira.mongodb.org/browse/SERVER-17262 started happening for us, we are also getting this error when performing a regular query:

Assertion failure dest->hasLoc() src/mongo/db/exec/and_common-inl.h 37

This is happening in production in a sharded cluster setup. There hasn't been any change to how we query or store data for a long time, but both assertion errors started happening recently and consistently. Not being able to query is breaking a critical path for us right now.

Any insights you may be able to share on this would be much appreciated.

Thank you!
