Web cache crashing

Question

Hello,
I recently noticed that our installation of web cache (9.0.2 - on Solaris 2.6) tends to crash often, up to several times per day. I have the auto-restart monitor running, so the impact is relatively minimal, however I'm concerned that this is happening at all.
I'm still investigating the logs, etc., so at the moment I don't have much specific data on what I think might be causing this (except that we are using ESI), but at least I would like to know if this is a known/common problem, and if so, are there web cache/9iAS patches/upgrades available that might help.
Thanks,
JK

We're just using the basic "include", here's a sample of what we generate dynamically from our app server, to our web server, and then to webcache:
<esi:try>
<esi:attempt>
<esi:comment text="serve html fragment"/>
<esi:include src="/content/pdml/customer/logo-flash.pdml" onerror="continue"/>
</esi:attempt>
<esi:except>
<esi:comment text="serve exception text"/>
<p>HTML fragment not available...</p>
</esi:except>
</esi:try>
It works well except for the occasional webcache crash (I suspect that certain types of requests are causing it to crash, haven't been able to narrow it down though).
Thanks,
