Yesterday around 2:30 our system did something unexpected.
Our system stopped responding to requests, and looking at the
CPU indicator, it was at 100%  Within about 25 minutes I got
one response on my session, then it "locked up" again.  I could
not get anywhere to find out what was going on, I couldn't even
log onto the console, as it normally logs onto QINTER unless 
we ENDSBS *ALL *IMMED then it switches to QCTL.

We had our F70 do this twice, the first time a RPG program went nusts and
started to produce a report in QSPL, it bombed before it finished so it left
a
huge member in QSPL but no output, the second time a new guy ran a query off
all
of our bigest files and dumped it to a new file. Both of these had no real
warnings in DSPLOG and I found them with a little program that I wrote to
find
the largest objects on the system, here it is if you need it:

PGM                                                       
                                                          
CHGJOB     LOG(4 00 *SECLVL) LOGCLPGM(*YES)               
                                                          
DSPOBJD    OBJ(*ALL/*ALL) OBJTYPE(*FILE *OUTQ *MSGQ) +    
             DETAIL(*FULL) OUTPUT(*OUTFILE) +             
             OUTFILE(MYLIB/OBJSIZE) OUTMBR(*FIRST *REPLACE)
                                                          
RUNQRY     QRY(MYLIB/QRYOBJSIZE)                           
           QRYFILE((MYLIB/OBJSIZE))                       +
           OUTTYPE(*PRINTER)                              
                                                          
                                                          
ENDPGM
