Please visit https://www.nbcs.rutgers.edu/~richton/richton-20061107-livelock_2.txt for an updated backtrace. This one almost looks like it has lock contention, and a writewaiter assert is notably missing...
The trace shows several threads backing off because they think some other thread is about to read the entry from the database. At a guess, none of them is actually going to perform the database read. Most likely a lock is missing here.
