sendsms interface

Hi,

 I have a web2sms system whereby I collect and
reformat messages from the web, then push them into my
kannel through the sendsms interface. If I push
messages rapidly through the sendsms interface using
lynx -dump '...', intermitently the interface goes
silent (i.e. empty response), and the message doesn't
get sent. Any ideas why? Is there some kind of
throughput limit? What can I do about it? Is there a
better way to send many messages through the sendsms
interface? 

Thanks.

B
