Runaway Realtime Processes

Runaway realtime processes can cause the system to halt or can slow the system response so much that the system appears to halt.

If you have a runaway process on a SPARC system, press Stop-A. You might have to do this more than one time. If this doesn't work, turn the power off, wait a moment, then turn it back on.

When a high priority realtime process does not relinquish control of the CPU, there is no simple way to regain control of the system until the infinite loop is forced to terminate. Such a runaway process does not respond to control-C. Attempts to use a shell set at a higher priority than that of a runaway process do not work.
