The load average includes disk wait blocking so in theory its accou
ng doesn't help,
even when experts are doing the guessing.) Bump up sendmail's queuing and
reject levels and give it another try.

How can I find out what is causing my problem "Connection rejected" on my

It can be difficult to tell without some sort of instrumentation or analysis
of how Linux is performing. At the first hint of a performance problem, the
typical solution in the Intel world is to throw more or bigger boxes at
it. We don't always have that luxury in the 390 world. Therefore alot

Its an inaccurate measure of the time to sit in a tight loop counting. Its
