FTP sessions won't open; FTP server is inaccessible


Applies To:

PAC Firmware running on:

  • SNAP-PAC-R1, SNAP-PAC-R1-FM, SNAP-PAC-R1-W, SNAP-PAC-R1-B
  • SNAP-PAC-R2, SNAP-PAC-R2-FM, SNAP-PAC-R2-W

Versions Affected:

All versions prior to R10.0h

Resolved In Version:

R10.0h


Symptoms:

If you are repeatedly opening and closing files or FTP sessions on a SNAP-PAC controller, eventually, attempts to open an FTP session will fail.

Workaround:

Limit the opening and closing FTP sessions and limit opening and closing files. A best practice is to keep communication handles to FTP sessions and files open if they will be accessed multiple times.

Resolution:
