How about the QDEVRCYACN system value?  The help text says: 
Device recovery action.  Specifies the action to take when an 
I/O error occurs for an interactive job's work station.

You know, I don't really remember just what we did. I was not 
directly involved
with this.....

I'm not certain if a CHGCMDDFT applied to ENDJOB would affect 
job abends. For
that matter, that could be a horrible fix if a job abends and 
you need the
joblog to identify the problem.

Perhaps you could write a simple CL program to issue an ENDJOB 
with LOGLMT(1).
Identify the message issued for your communications failure and

CHGMSGD MSGID(xxxnnnn) MSGF(msgfile) DFTPGM(yourENDJOBPGM)

hth. Just one idea....

Eric !

Where/how do you use this ? I see that the ENDJOB command has a 
field for this
information, but if the system is ending these jobs due to a 
communications
failure,
how do you handle this ?

We have had the same thing happen. We have had a NIC start 
beaconing or have had
a
frame realy failure OR the one of the NIC cards in our AS/400 
has "burped" and
all
of a sudden we have 400+ Client Access devices in the US and 
Canada
failing/writing
MASSIVE job logs...

Thanks !

Chuck
