While doing some local stress testing, I hit the following assertion failure:
mongos.exe!mongo::breakpoint() Line 60 C++

The offending line is here and it looks like the input opType is 2008 (dbCommand) and the expected value is 2006 (dbDelete).
It looks like the mongo shell is sending a command, but mongos does not support commands.
The command being sent looks like replSetInitiate:
