FWIW, the other guy I know who is having this problem had already switched to using ULE under 7.0-release, and did not have any problems with it. So *his* problem was probably not related to SCHED_ULE, unless something has recently changed there. Turns out he hasn't reverted back to 7.0-release just yet, so he's going to try SCHED_4BSD and see if that helps his situation. -- Garance Alistair Drosehn = gad@gilead.netel.rpi.edu Senior Systems Programmer or gad@freebsd.org Rensselaer Polytechnic Institute or drosih@rpi.edu
