Again DLFM Server start up problem

[afvaiv <afvaiv@xxxxxxxxxx>]

One week ago I posted the following problem:
Sorry for this lengthy message, but I'm DEAD STOP !
-------------------------------------------------------------------------------------------------------------

Hi, I've started to use DLFM to deal with links to picture fields, etc
for a new app.
I'm following steps as detailed in redbook SG24-5409-00

After setting up my RDB, INZDLFM, add Prefixes, add Host DB, etc, I come
to "Start TCP Server *DLFM".
It runs for some time, and at the end I get following messages...

TCP1A0F : DLFM Server starting

Wait for DLFM Server jobs to Start
Unable to Start DFLM Server

but then I go to QSYSWRK Subsystem: the redbook mentions there should be

(p.164) 8 jobs running (with names starting with "QZDFM...") but I only
get 7 up and running. The missing one is "QZDFMCHD"...

Any one knows why this job did not start as the rest did?
7 out of 8 is the reason for message "Unable to start DFLM Server" ?
-------------------------------------------------------------------------------------------------------------

Got two answers:

One of them suggested to look at QZDFMCHD joblog (it's the missing
job!); try to change the joblog, or even look DSPLOG or the other 7 jobs
joblogs...
The other one, suggested 3 APARs...

Well, for the first one, there is no joblog. All other 7 jobs use
JOBD(QDFTJOBD) so I changed it to LOG(4   00 *SECLVL) but still no
joblog for the missing one... I looked in DSPLOG, and I see 7 jobs
starting and then ending, which (I guess) just start the 7 ones that
keep alive. But not 8 of them.
Still, got joblogs for all of them, and no clues !
More strange yet, if I ENDTCPSVR *DLFM, it takes a while... says "Server
terminated"... but the 7 jobs are still up !
I can do ENDTCPSVR once or several more times... and no protest, it
takes some time and end saying "Server terminated"... !!! but 7 jobs
still up !
I guess it should either really terminate the 7 jobs, so I could not say
ENDTCPSVR again and again... or else say, I cannot terminate it for some
reason, or not?
If I don't kill myself the 7 jobs and try to STRTCPSVR *DLFM again, I
get "Server started" , but it is NOT true, since I can see it is stopped
thru Ops.N...
Even trying to start it thru Ops.N. won't start it. Right clicking on it
I just get same 7 server jobs as doing it manually, no matter how many
times I try it.
Only if I "do" kill the 7 jobs myself, and then try  the STRTCPSVR
again, then I DO get again the messages

TCP1A0F : DLFM Server starting

Wait for DLFM Server jobs to Start
Unable to Start DFLM Server

but still server appears as stopped under Ops.N.

Anyway, if I try to insert a record in the table (where it should be)
with SQL, I get error SQL0357 saying file server for datalinks is not
available...

Well, now I'm in a dead-end. Don't know how to go in any direction...
