APAR Error Description / Circumvention 

DESCRIPTION OF PROBLEM FIXED FOR APAR SE03553 :

-----------------------------------------------

  QTSMTPSRVP job has high sustained CPU. Traces indicated several

  pages of writing to FSO in small bytes (2 bytes) at a time.

 

 

CORRECTION FOR APAR SE03553 :

-----------------------------

  When parsing a message, SMTP was sending a few bytes at a time

  to be written to an FSO.  Each time a write is performed, trace

  statements are recorded and a separate program is called to

  write to the FSO.  Even a small message results in a large

  amount of trace statements and calls to the FSO write program.

  SMTP will be modified to store data in a 32k buffer before it

  is sent to the FSO.  Unnecessary trace statements will also be

  removed.

  Also, using this APAR to put in the SMTP portion of the fix for

  APAR SE03492.  This change will modify the local test code to

  treat IP addresses 0 or loopback as remote.  Thus, the SMTP

  Client MX resolver code will get the mail, and be better able

  to handle hosts who have 0 or loopback IP addresses for A

  records with valid MX records out on the Internet.

  Cleaned up a the call to the message processing procedure in the

  SMTP Client Prestart Job.

 

CIRCUMVENTION FOR APAR SE03553 :

--------------------------------

 

  None.

 

 

 

DESCRIPTION OF PROBLEM FIXED FOR APAR SE03605 :

-----------------------------------------------

  QTSMTPCLTP

 

 

CORRECTION FOR APAR SE03605 :

-----------------------------

  In the SMTP Server Daemon,  an error occurs when handing off

  an SMTP connection from the Server Daemon to a Server Prestart

  Job.  In this situation,  the handoff is started,  but can't

  complete successfully because the SMTP connection ended before

  it could be handed off.  Error checking was added so that if the

  Server is unable to hand off the SMTP connection,  the Prestart

  Job will be ended or it will continue to wait to receive the

  connection.

 

CIRCUMVENTION FOR APAR SE03605 :

--------------------------------

 

  None.

Lied to again!  SMTP doing same thing this morning, except it is deleting
data area and then taking CPU.

I'll take that PTF info if you can get it Carl.  I searched IBM's site and
found a bunch of things, but nothing specific to my problem.
