Synapse bulk upload issue

In my application I generate a few hundred php files. I try to upload
them using Synapse. Except that the upload is not as fast as a
standard client like FileZilla, the application runs well for around
80 files and then terminates due to a boolean false in the sendfile. I
tried different settings, active, passive, binary etc. but no success.
Does someone have had the same experience or can point me to some
error? I tried getlasterror, but it gives a 0. I can't figure out how
to trap the socket error (if there is any).

The structure is simple:

- read files from folder
- open ftp
- for each file
-    sendfile
- close ftp

Reduce the local stack size to 2048 instead of the default compiler
settings.

I changed the stack size on the compilation and linking section in
project options and set it to 2048.
But there is no difference in behavior unfortunately.

Ok, if the upload fails then just logout, do a login and retry. Then
it goes well for again around 80 files etc. Don't know why, but if
this does the job. Still I wonder why there is such a dramatic
performance difference between Synapse and Filezilla.
