You could try to capture the UDP packages at the client and try to find
anything suspicious.
I came only up with one guess (since you claim the latency is fairly
ok): Somehow the UDP packets arrive in a different order than they were
sent. I believe the code cannot handle that currently.
Currently the only relevant tunable is udp-seek-threshold, but it does
not apply when the timestamps jump backwards.
If the issue is what I guessed, I think the fix is to add a counter
field to the timestamp data sent and ignore outdated ones.
Or something like that.
