<font face="arial" size="2"><p style="margin:0;padding:0;">Hi Emile,</p>
<p style="margin:0;padding:0;"> </p>
<p style="margin:0;padding:0;">Thanks for your reply.. Unfortunately, it is impossible for us to guarantee that a msg will be acked by the same channel. We are connected to tcp over 3G so we're lucky if the connection is up for 45 secs...</p>
<p style="margin:0;padding:0;"> </p>
<p style="margin:0;padding:0;">Can you give me an idea how serious a problem, performance wise, it is to have the msgs unacked like this?</p>
<p style="margin:0;padding:0;"> </p>
