I just noticed something strange. It isn't exactly that the HTML is
cut off. All of the parts match the output on my dev server. But it
looks like the HTML has been chunked up and mixed up, for lack of a
better way to describe it. For example one of the pages has two head
tags, but is missing some of the other chunks.
Here's an example line from the dev server:
<tr class="standardTable_Row1" onmouseout="restorColors(this,8)"
onmouseover="changeColors(this)"><td
class="standardTable_ColumnRight">Snapnames
</td><td class="standardTable_ColumnRight">223</td><td
class="standardTable_ColumnRight">1.79%</td><td
class="standardTable_ColumnRight">4</td><td
class="standardTable_ColumnRight">50.00%</td><td
class="standardTable_ColumnRight">2</td><td
class="standardTable_ColumnRight">$1.00</td><td
class="standardTable_ColumnRight">$2.00</td><td
class="standardTable_ColumnRight">$4.00</td><td
class="standardTable_ColumnRight">2</td></tr>
And here is the same line from production server:
<tr class="standardTable_Row1" onmouseout="restorColors(this,8)"
onmouseover="changeColors(this)"><td
class="standardTable_ColumnRight">Snapnames
</td><td class="standardTable_ColumnRight">223</td><td
class="standardTable_ColumnRight">1.79%</td><td
class="standardTable_ColumnRight">4</td><td
class="standardTable_ColumnRight">50.00%</td><td
class="standardTable_ColumnRight">2</td><td
class="standardTable_ColumnRight">$1.00</td><td
class="standardTable_ColumnRight">$2.00</td><td
class="standardTable_ColumnRight">$4.00</td><td
class="standardTable_ColumnRight">2</tlumns:</span></td></tr>
That is the first place where the html deviates. After that follows
another chunk of html that should appear further down the page. I'm
baffled. Anyone know what could be causing it?
The problem seems to appear only on longer pages. I haven't gotten
the 503 error lately, the TimeOut and KeepAliveTimeout directives
might have fixed it.

I added
TimeOut 1200
KeepAliveTimeout 30
To the end of httpd.conf which didn't fix the original 503 problem. I also
noticed that sometimes I don't get the error at all, but the html response is
incomplete. I will experiment some with %D and see if I can learn more about
the problem. In the meantime, I would appreciate any ideas you all might have.
Thanks,
