Thanks for the reply, Whit!<br><br>Perfectly reasonable first question. The websites have user-generated content (think CMS), where people could put in that kind of content. The likelihood of such a scenario is slim-to-none, but I'd rather not have that kind of vulnerability in the first place. And yes, we could also add in validation and/or stripping of content that is outside the bounds of normal, but the main reason I bring up this Page of Death scenario is that I worry that it may be indicative of a weakness in the system that a different kind of load pattern could trigger this kind of hang.<br>
<br>To answer the second question, running top on the Linux side during the Page of Death (with nothing else running) I get a CPU % spike of anywhere between 80-110% on glusterfsd, and 20% on glusterfs, with close to 22GB of memory free. The machines are 16-core apiece, though. On the Windows side there is next to no effect on CPU, memory, or network utilization.<br>

</div>Off topic response: Is there ever in real production any page, anywhere,<br>
tht contains tens of thousands of image references? I'm all for testing at<br>
the extreme, and capacity that goes far beyond what's needed for practical<br>
purposes. Is that what this is, or do you anticipate real-life Page o' Death<br>
scenarios?<br>
<br>
Closer to the topic: What's going on with the load on the various systems.<br>
On the Linux side, have you watched each of them with something like htop?<br>
