well, life would be too easy if two bugs were fixed at once ;) These were nodebug runs, right? Could you give me a description of the precise commands of how you started jackd and fluidsyth (and their versions) - so that i could try to reproduce & debug your setup. It is certainly a complex scheduling scenario.
(perhaps with a link to the .sf2 and .mid files you used, if they are public - or whether it's fine if i use the VintageDreamsWaves-v2.sf2 sound-fonts that comes with fluidsynth plus a random .mid file from the net?)

Do you know when this started, roughly?
