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

[Christine Krebs <christine.krebs@xxxxxxxxxx>]

   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

     Hi Christine,
     That's strange -- I haven't run into that problem before.� � Could
     it be that you are running out of descriptors?� Maybe you're
     forgetting to call FTP_quit() in some cases (like, if there's an
     error?) and therefore it's never cleaning up the descriptors, so you
     eventually run out?
