@manan Odd... seems it just means the connection to Mongo was lost... have you tried force-killing Mongo and restarting it?

[manan]

@julian the issue was different mongodb versions on different servers, when the database migrated on the different version of mongodb it failed with that error periodically. The odd thing is it did not crash, just hung threre.
