Before doing the 64-bit tdb just for messages.tdb, I would
rather go and rip out messages.tdb overall and replace it
with something like the s4 messaging system based on unix
domain sockets.

messages.tdb with 3.5GB is a bug somewhere else. A 64-bit
tdb implementation will not help you there. You might want
to look if the system has smbd processes in state D for
extended periods of time, which would give a hint towards a
kernel bug or a hardware problem.

Can you take a look in the system if you have such D state
