Re: AS/400 Locking up

Some more detail

1.) "Twinax stopped working" - I use a twinax terminal for the system console, and when the "lock up" happens, the screen goes blank with the cursor in the upper left hand corner.

2.) A system job taking a lot of CPU - I have noted that while the DASD units are on, but I do not hear any noise like the heads moving etc.  First time it happen, the system is in the "locked" state for over 18 hours before I turned it off on the advice of IBM.

3.) somebody has a changed job to a priority - I work for a small company.  I am the only one here that knows that there are priority settings that can be changed.  I am the only "computer" person here (aka the computer guy).  I know of every code change that has taken place for the last 4 years.  The "lock ups" have mostly happen when no one was in the office.  Only once did it go down during the business day.

4.) SMTP Spammer - I do use AS/400 to send email.  In the early weekday mornings, I use job scheduler to run some reports, split them and email them.  I was a worried about someone using the AS/400 as a relay so I used CHGSMTPA to set ALLMAILMSF = *NO.  I don't think this is the lock up problem, but it's an important issue anyway.  If I kidding myself that ALLMAILMSF = *NO will stop mail relay, please tell me.  If someone knows a better way to stop Relay mail, I am all ears.

5.) Journals - It takes a lot for me to say this, but I have no clue about journals.  What are they?  How do I know if any are running?

6.) DASD - 73% used of 25 GB

7.) I already sent Bob Worlton a PM, and he is going to help me out.  Thanks Bob.  Whatever the outcome is, I will post to the list.  Now I am praying it's a hardware/software issue, or I am going to feel like a total idiot.

Please keep the ideas coming.

Thanks,
Joe Lewis
