PM70922: NETVIEW/FTP SERVER LOOP. NFTP NETVIEW FTP

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• A NetView/FTP SNA server went into loop when attempted to
  transfer a PDS dataset.
  The loop occurred in module DVGMSPO around offset 2da4 - 2dea.
  This happened when a member of the PDS dataset contained a
  wrong record. The dataset was RECFM=VBM and there was a record
  which Length field in the RDW was zero.
  When attempted to print the contents of the member by using
  AMS PRINT, IEF036I 002-04 error was issued. The RC=4 indicated
  "The RDW specifies a length less than 4."
  The trigger of the loop was a wrong dataset but the server
  should avoid such a loop.

  RDW=0 is not allowed, but it could be due to a file corruption.
  In this case we must avoid the neverending loop.
