<div>Bret,</div>

<div>Thanks for the reply - that appears to put us (perhaps) a little closer. I'm assuming for the moment when you said "init script" that you meant the script I use to call up varnish and not the script that boots the box as per /etc/inittab. When I specify "ulimit -s 1024" it did not change the net result of varnish's inability to create threads:</div>
<div> </div>
<div> 192 N worker threads<br> 424 N worker threads created<br> 62 N worker threads not created<br></div>
<div>However the C program I posted previously in this discussion was able to create 3055 threads. Hope that helps.</div>
