<p class=MsoNormal>Hopefully your upper management allows you to install
contemporary software and distributions. Otherwise memory leaks and
x86_64 would be the least of your concerns. Honestly, you're waiting for
Varnish to stabilize and you're running v1?<o:p></o:p></p>

<p class=MsoNormal>My data point: 5 months and over 100PB of transfers, and
2.0.4 is stable and has <i>never</i> leaked in our pure x86_64 production
environment. Its memory use can be precisely monitored and controlled
between Varnish configuration and the OS environment by any competent sysadmin,
IMHO. We actually can't use Squid at all because it really <i>does</i>
leak like a sieve. pmap does not lie.<o:p></o:p></p>

<p class=MsoNormal>I just hope that people that have problems with any software
are taking on the responsibility of diagnosing their own environments as much
as they expect any OSS project to diagnose its code -- the former is just as
often the problem as the latter.<o:p></o:p></p>

<p class=MsoNormal>I experienced this same issue under x64. Varnish
seemed great but once I put some real traffic on it under x64 the memory leaks
began and it would eventually crash/restart.<br>
<br>
Ended up putting Varnish on the back burner and have been waiting for it to
stabilize before even trying to present it to upper management again.<br>
<br>
Varnish has great potential but until it can run stable under x64 it's got a
long fight ahead of itself.<br>
<br>
(I do want to note that my comments are based mainly on varnish 1 and not
varnish 2.0)<br>
