Talkback server seems to have been down for more than 48 hours. Notice the following near the bottom of http://talkback-public.mozilla.org/search/start.jsp There are currently 103826 incidents waiting to be processed by the Talkback server. The next incident id in the queue is 44960403 and was submitted on 2008-05-09 19:09:04.0. Based on that information, some of your incidents might take a while before they show up in any queries.
Yes, this is known and is in my hands.
For the record, KEY_VARCHAR_INDEX had filled up a datafile. I created a new one (key_varchar_index04.dbf) and Talkback is processing again, however there's a larger problem that we're working on. It's going to take a couple of days to work through the backlog.
It's slow but yes, it's processing again. Thanks Samuel.
