Re: System slow

[Pete Helgren <pete@xxxxxxxxxx>]

An open relay in the SMTP server was a problem on one of my customers 
boxes.  It was very busy sending out all that SPAM. That would, however, 
stay pretty consistent once the open relay was exploited.  Only getting 
10 minutes of slowdown makes it a bit of a challenge to sort out, after 
the fact.  Have you had another occurrence?

No interactive sessions were knocked off or ended and no errors for controllers were shown on qsysopr during this 10 min period.  Qsysopr shows only a few jobs running during the 10 min period and those jobs are rountinely run during the day.
