PM49027: FTP SERVER ABENDS WITH 878 OR HASP310 ERROR DUE TO STORAGE GROWTH WHEN USING JESINTERFACELEVEL 2

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• A FTP client is connected to the FTP server doing repeated
  commands using JESINTERFACELEVEL 2.  Each time the client
  submits a LIST or NSLT command which does not find any JES jobs
  available for the specified JESJOBNAME, JESSTATUS and JESOWNER,
  a STATMEM call is not issued.  This causes a 64K STATSTOR
  control block to be leaked in Subpool 230 Key 1.  If enough NLST
  or LIST commands are done, the FTP server address space will
  eventually run out of storage.  An 878 abend or a 40D abend will
  be seen.

  ****************************************************************
  When FILETYPE is set to JES on the FTP server and repeated DIR
  or LS subcommands are processed but no jobs are found, then
  storage is not freed correctly.  Each time the FTP client
  issues a DIR or LS subcommand which does not find any JES jobs
  available for the specified JESJOBNAME, JESSTATUS and JESOWNER,
  a STATMEM call is not issued.  This causes a 64K STATSTOR
  control block not to be freed in Subpool 230 Key 1.  If enough
  NLST or LIST commands are done, the FTP server address space
  will eventually run out of storage.  An abend 878 or 40D will
  be seen.
