Blocker - P1 MongoDB Version: 2.4.5
OS: Win Server 2008 R2 SP1
Config Server: 3 instances.
Sharding: 2 shards
Replica set size: 3
Issue:
MongoDB is readable but not fully writable. For example, issuing a command as below:
db.collection.update({Active:true}, {$set: {field: value}}, false, true);
The command will update only one record and then receiving error message simply saying "!loc.isNull()".
I have also observed frequent log entries in mongos.log
