while trying to split a chunk manually, the server responded with an assertion error and data retrieval was not possible.

I'm attaching the cunklist (db.printShardingStatus as well as a mongos log file that contain the events)

What can i do in order to split the chunk? right now the index is not even on 2 of the shard servers.
