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.
