This will reserve a bunch of process table slots, which you will be able to use via "exec", the idea being that if you can't fork new processes, you can at least use exec to replace an existing ksh process with something else. This will hopefully give you some limited ability to run a few post-mortem diagnostic commands before you run out of reserved process table slots. -ken
