Problem conclusion

Temporary fix

Comments

• CSSMTP is amended to check the storage resource after each
  completed message.  If storage is constrained message EZD1858I
  is issued and mail processing is automatically suspended.
  Once the storage constrained is relieved message EZD1859I is
  issued and the reading of mail messages from the spool
  resumes.
  
  The MODIFY jobname,SUSPEND and MODIFY jobname,RESUME are still
  supported.
  
  The response to the command MODIFY jobname,SPOOLSTATUS now
  includes a new task status: WAITS. The JES spool task is
  waiting for storage.
  
  The following documentation changes are required:
  
  z/OS Communications Server
  IP System Administrator's Commands
  Document Number SC31-8781-10
  Document Number SC31-8781-12
  
  In Chapter 1, "Operator commands and system administration",
  under "MODIFY command: Communications Server SMTP application
  (CSSMTP)", "Example 5: The MODIFY DISPLAY,SPOOLSTATUS"
  "STATE  This parameter can have one of the following values:"
  insert the following:
  
  WAITS  The task is waiting because virtual storage is
  constrained.
  
  Under "state  Possible values are:"  insert the following:
  
  WAITS  The task is waiting because virtual storage is
  constrained.
