ap_pass_brigade failed in handle_request_ipc function
A page is resulting in a 500 error and the log shows this:
[Wed Mar 20 11:19:23 2013] [warn] [client 127.0.0.1] (104)Connection reset by peer: mod_fcgid: ap_pass_brigade failed in handle_request_ipc function
It is occuring on a lemonstand website, when you try to view 90 products on a category page. The step from 60 per page to 90 appears to be too many, and it results in a 500 error.
The page loads for no more than around 4 seconds before the error, and there are many other websites running on the server which do not experience this issue.
I have so far assumed that this is due to environment settings, and not caused by Lemonstand. I have googled the heck out of this and tried various config settings to get it to behave, none have so far fixed it. Below is the current fcgid config, I have commented out some of the variables I tried changing.
Fcgid.conf:
<IfModule mod_fcgid.c>

Answer
This is a PHP-FCGI limit error you're receiving. You'll need to adjust either the "PHP_FCGI_MAX_REQUESTS" variable inside the "fcgi-bin/php5.fcgi" file for the domain or "FcgidMaxRequestsPerProcess" variable inside the Apache config file.
