_updateSourceField error

[MatejJan]

I've encountered this issue after manually deleting a document from the database using MongoHub (in case that makes any difference).

My server also started running rapidly out of memory around the same time, so I hope this is not connected. I'm trying to identify the source of any corruption in the DB or anything like that to get a hint on what's going on. This is the first exception I can find that's appearing around my issues.

Any update on this? If you delete a document out of order it might have an update which it cannot anymore apply, so it complains.

[MatejJan]

I haven't ran into this issue again, and the server overloading happened for some other reason (a complex templating system that probably created a huge number of subscriptions).

[mitar]

OK, then I am closing this.
