This is how it looks like (a synthetic test, not an actual problem happening in real world: >>> y3 UID THREAD REFS utf-8 ALL <<< * THREAD (1)(2)(3 4) <<< y3 OK thread LOG 1 "ThreadingMsgListModel for a" "ThreadingMsgListModel::wantThreading: THREAD contains info about UID 4 (or higher), mailbox has 101" >>> y4 UID THREAD REFS utf-8 ALL The code should probably detect that the server is broken and not keep asking for the same data over and over again; that would be rather expensive, data and CPU-wise.
