Hi Adrian, <br>
<br>
<br>
This patch is looking good as yet, I've repeated tests that
were <br>
previously causing timeouts and as yet not been able cause a
timeout <br>
after applying this patch. <br>
<br>
Its not definitive but so far it appears to have resolved
this issue <br>
for me. <br>
<br>
<br>
Regards, <br>
Vince Hoffman <br>
