This rings a bell. I made some stupid programming mistake that under certain circumstances caused the CPU to be 100% busy. The console serial line was the only way in to find out (dm windows stayed blank/white because there was no CPU time left. It appeared dead). As far as I remember this was on vxWorks 5.3.1 and some earlier EPICS 3.13 though.
