I run a high volume service and up until recently I have had nothing to
add as we have have only been affected by this issue once. However, in
the last couple of weeks we have had this happen to two of servers.
Within in 20 minutes the queues had grown to unexceptable levels and the
LA on the box jumped hugely. It took me over an hour to track down
which message caused the issue (as an aside - adding the message back in
to the processing queue about an hour later and it went through fine!).
I for one would have accepted the the tiny hit a few SQLite queries per
message would have caused had the code been avalible then. I hope to
have the code in production by the end of the week
