Hi,

The "blocking call cancelled" error is actually from within WS_FTP and 
your local computer.

WS_FTP suggests the following solution if you receive one or more 
"Blocking call cancelled" messages and the file transfer is incomplete:

If you are using the Microsoft TCP/IP stack, part of the Windows 95 and 
NT operating systems, try setting the Maximum Transfer Unit (MTU) to 576.

For more information on this error see IpSwitch's Knowledgebase article: 
http://support.ipswitch.com/kb/WS-19980612-BK21.htm
