Thanks Daniel and Michael..

Michael offered a very good suggestion. I followed this and came to realize
that the problem is somehow related to multi-threading. in our code if I
replace
    pthread_create(&lv_thread, NULL, &sendfile, (void*) lp_fil);
with
    kesftp_sendfile(lp_fil)

In sendfile(), the actually uploading using curl is implemented.

then it works.

But the transmission is quite slow so it's not acceptable for the server
program. And it would be too much work to upgrade the libaries within the
timeframe we have.

Do you have any suggestions?

Thanks!
