Are you using the latest Voyager Version, 15.1.0.0 is the latest.

Note the latest bugs:-

Corrected a problem where FTP Voyager's CPU usage would increase over time, when downloading very large files, using excessive amounts of CPU time.
Corrected a bug where FTP Voyager would incorrectly create a local directory while using folder locking and uploading nested directories.
Corrected a bug when parsing MLST/MLSD results where certain Asian characters could cause FTP Voyager to hang.
Corrected a bug where FTP Voyager was not allowing "level 1: CA certificate" (the second level) and higher Certificate Authorities to be verified.

Do you have dangling objects in the VFP Code?

>Does anyone out there use FTP Voyager to call VFP programs? We have a number of processes that transfer files to and from various entities. Recently the server these were running on (actually a PC running XP Pro) died, and we have moved everything to a new server running Windows 2003 Server.
>
>The setup is very straighforward (FTP Voyager allows automated login for FTP file transfers, and it can also execute programs), and no changes were made to the programs that run. The basic practices are that a VFP exe is run and the file it generates is uploaded or a file is downloaded and a VFP exe is run.
>
>Most things on the new server run fine, but some VFP exe's do not appear to "clear" completely and FTP Voyager hangs. Anybody have an clues? TIA for your help!
