Hello Luke. Well, I already checked that. The cell is being deallocated from a secondary thread but there is nothing in the thread that indicates what triggered it. It looks like a performSelector:withObject:afterDelay: or something like it but we don't have any of those in the table view controller that controls the table view. Like I said in my original message, I've looked for any flavor of UITableView reload… and the only calls we have are reloadData but they are all executed on the main thread using [[NSOperationQueue] mainQueue] addOperationWithBlock: so I'm stumped as to where this deallocation is triggered. I've checked all the other running threads and I can't find any code that you reload the table view which could cause its cells to be deallocated.
