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.
Well, one of my machines just locked up again, even with SCHED_4BSD
on it, so I am now thinking it is unrelated.
The machine has completely locked - no response to pings, no
response to keypresses, nor to the power button. There is nothing
printed on the console - it is just sitting there with a login prompt :-(
This is really not good - these are extremely common servers after all, and
I am just running bog standard 7.1 with apache and mysql. This is happening
across several different servers, all of which are slight variants on
the DL360, so I dont think it is something perculiar to me.
