PM80550: REIN COMMAND CLEARS THE INACTIVE TIMER

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• An FTP client issues a REIN command, which is intended to reset
  the session to require a new login.  But as a part of this
  processing, the configured value for the INACTIVE time is zeroed
  out.  This can cause the associated FTP server address space to
  remain indefinitely, instead of terminating after inactivity for
  the configured time period.
  
  For most instances, this may not be noticed since the remote
  client's termination of the session will normally cause the
  server process to end.
  

Local fix

• An FTCHKCMD exit can be written to either reject the REIN
  command or convert it to a QUIT command.

  * RECOMMENDATION:                                              *
  ****************************************************************
  In the function of processing REIN command, the server FTPDATA
  statement INACTIVE value is cleared out to zero. This causes
  that the server address space will wait forever for the next
  command, instead of terminating after inactivity for the
  configured time period.
