In my case, I added printf statements to trace the fcntl calls and it was

locks on RedHat 9.
I do not see how this is possible, unless you are sharing sqlite3*
handles
between threads (a strict no-no). I've sent you the instrumented
os_unix.c
file separately. Please prove me wrong...
I've temporarily placed the trace file at
http://67.19.10.2/~crpalmer/sqlite-traking.gz
The problem is occurring with the first failed lock (ie, if you search for
"failed" that is where the problem occurred).
Let me know how I can help debug the problem.
Cheers,
Chris.
