Re: FTPAPIR4 FTP Error 15 (Unable to create socket)

[paul.roy@xxxxxxx]

   Hi Christine,
   could it be a missing close(); in a program processing one of the IFS
   files ?
   I think you could use
   CALL PGM(QP0FPTOS) PARM(*DUMPLFS  &JOBNumber)
   to print a list of open files
   that could eventually help to undestand the cause ...

   Scott -
   This is what it would seem like but we are calling the quit every time.
    I
   can see the FTP QUIT command in the FTP audit log as well.
   The only way to reconnect is for the submitted job to end. I haven't
   had
   any luck trying to loop back and reconnect.
   Thanks,
   Christine
