Re: CPU at 100%

[Chuck Lewis <clewis@xxxxxxxxxx>]

Jim,

You can DEFINITELY do what Mark suggests and I have done that but that does NOT
guarantee that you will be able to do anything. Sometimes yes, sometimes no. We
had this happen several years back and could get NOTHING out of the console 
after
keying in one command and pressing Enter. This was on a 530 running V3R7 with 
500
users. I called IBM and we did a dump. They found that is was a problem in a 
call
in a BPCS program...
