QuickReport 3.6.2 QRPDFFilt prob

I am trying to create an application that will download log
files from a server every hour.  The application works ok,
but the problem is I get the following error on occasion.  

An exception occurred when performing the FTP getfile
operation.
The cause of this exception was that: IOException caught
while copying..

I need to add that this happens only with large files.  Like
150 mb.  It gets about 3,000 kb downloaded then throws this
error....

Any ideas on how I can get around this?  Or has anyone seen
this before?
