2135.0. "x400recv process does not exist" by KERNEL::SIMPSONR (fred) Wed Feb 19 1997 18:20

URGENT PROBLEM.......
LinkWorks V3.0.7  Unix V3.2c

I have a customer who has no mail going from his MTA to /usr/spool/mail/in
If he does:

 ncl>show mta mpdu *  all

He can see all the mail messages queueing up for LNX. In /usr/spool/mail/in
there are no mails. He does not have a x400recv process running and in the
X400recv.log it says:

 Wed Feb 19 12:03:55 1997: can't find X.400 address of rtd001s
 Wed Feb 19 12:03:55 1997: can't find X.400 address of rjk001
 Wed Feb 19 12:03:55 1997: can't find X.400 address of mfc001
 Wed Feb 19 12:03:55 1997: can't find X.400 address of ap004
 .....

much later:

 Wed 19 12:03:56 1997: forced exit
   529 X400 error (16) OMNOT_PRESENT

Why has the X400recv process died, why is there only info in the log file from
12:03 when XMPROC was started early this morning?

Any ideas?

2135.1FTBP received ?UTROP1::schimmb.uto.dec.com::schimmel_bThu Feb 20 1997 08:1915
Richard,

The x400recv.log tells that the x400recv program was started 12:03:55.  Directly thereafter it 
gets a message which needs to be processed resulting in the error OM_NOT_PRESENT.  It is 
considered fatal (in the x400recv program) and therefor it stops.

You can get more information if you activate tracing (cd /usr/op/servers/extmail; ./xmstart -t4).

I have seen this error (OM_NOT_PRESENT) once before.  It happened when a body part 15 of type FTBP 
(as normally sent by MS-Exchange) came in.  If this happens (FTBP coming in) you need the latest 
MTA which converts FTBP to a tagged body part 15.  Alternatively you need a later version of 
LinkWorks external mail which reacts differently to the OM_NOT_PRESENT error (sending an error 
message to the sender).

Hi,

We ran ./xmstart -t4 and it created a new x400recv.log and it told us nothing
different to the original!

Would it be possible for the customer to go to external mail V3.08, rather than
upgrading the whole of LinkWorks? If so what is the patch name...

To get the customer running can we go into NCL and delete the first message so
that all the other messages go through?

Cheers,
Richard.

Customer has stopped and started xmproc many times and it then allowed the
x400recv process to stay running for about 1/2 hour then it died again. He has
done some tests and it appears to be any remote mail that causes the problem.
They have done no alterations on their system as far as they are aware.

Where can we go now?

Cheers,
Richard.
2135.4Maybe a trace gives some more infoUTROP1::kampenp.uto.dec.com::SCHIMMEL_BFri Feb 21 1997 09:059
Richard,

I don't understand this at all.  Maybe I can get a feeling for this problem when I have a log file 
with a dump of a  received message making x400recv stop.

Please try making a trace (cd /usr/op/servers; ./xmstop; ./xmstart -t4) and mail me the file 
x400recv.log (at least when it contains a message dump).

 Hello Berd,

 Thanks for your time on this problem. We have resolved the issue by:

  Kept killing off and restart the xmproc process
  There were five messages in the MTA not being delivered
  Killed them all
  Took a note of the originators, then one sent another message and it hang
   again
  He then found that these users were sending mail to a different server (EXP3)
  but that it got routed by the server (EXP4) with LinkWorks on it. He checked 
  EXP3 and found that its mail services were down. He restarted these, the user
  recent the document and it went through fine and the LinkWorks X400recv had no 
  problems.

 Problem solved closing call,
 Cheers,
 Richard.
