Re: Can three looping processes, zero priority, affect performance significantly?

Cache sets the no delete bit to prevent processes in Cache from being deleted with the STOP/ID which can cause nasty things with Cache.

Re: Can three looping processes, zero priority, affect performance significantly?


Would I be correct in saying by the time a process is in this cul-de-sac, it's too late to clear the NODELET bit, since it will not call delprc again? I have just seen two of these badly terminated cache processes here (basically the same environment as you Clark).

It seems like it would be possible to clear the bit and then send a special kernel mode ast to make the process call delprc again? (or do both in the kernel ast.

This is a bug in cache I guess, which is letting these processes exit the cache databaseenvironment without clearing the bit.
Can you imagine if we used PCs to manage our enterprise systems? ... oops.
