We are get continuosly this exception message: "initial sync exception: 10083 create collection invalid size spec" each time we try to start up one of our shards.
We have been looking for corrupt collections and documents all over the system as it looks to be related to a bson object size, but can´t find why this is happening over and over, and there is not information about this error message. Also, we had tried db.repairDatabase() and get the same exception on both shards.
We found where this is generated on cpp code on git https://github.com/mongodb/mongo/blob/master/src/mongo/db/pdfile.cpp at line 276
thanks in advance, help will be welcomed
