However, if that message isn't "normal", it can indicate an attack on the system. For example, ACBs (activity control blocks) are used whenever there is something to do. I once saw a stack get hit with several hundred simultaneous telnet sessions and it got an ACB shortage. In this case it was semi-legitimate (a misconfigured test program), but I wouldn't update the control block allocations to make the message go away. I *want* to know something like that is going on. If you get the messages on a regular basis, then it may just reflect "normal" cycles in your workload and you *should* increase the buffer pools to reflect what is normal for your system.
