Hi folks, I have a Radiant install running Apache/FastCGI on linux. FastCGI keeps crashing when it tries to load too many pages at once. Here’s how I reproduce it: 1. Clear cache 2. View site - open about 10 pages, one right after the other. 3. FastCGI will crash with “Premature end of script headers” 4. Several (not all) of the pages will return a 500 error. Fcgi generally recovers and the pages that failed will be loaded correctly if you refresh the browser. The production.log shows nothing out of the ordinary. Here’s the production log after clearing the cache: Processing SiteController#show\_page (for --.–.--.— at 2007-10-03 10:14:51) [GET] Parameters: {“action”=\>“show\_page”, “url”=\>[“campus-life”], “controller”=\>“site”} Completed in 1.41990 (0 reqs/sec) | DB: 0.08094 (5%) | 200 OK [http:// studentlife.biola.edu/campus-life/] Here’s an excerpt from the apache error.log: [Wed Oct 03 10:06:27 2007] [error] [client 75.–.—.---] Premature end of script headers: dispatch.fcgi, referer: http:// studentlife.biola.edu/ [Wed Oct 03 10:06:28 2007] [error] [client 75.–.—.---] Premature end of script headers: dispatch.fcgi, referer: http:// studentlife.biola.edu/ [Wed Oct 03 10:06:28 2007] [notice] mod\_fcgid: server /home/----/ studentlife/releases/20070716223737/public/dispatch.fcgi(9683) started [Wed Oct 03 10:06:28 2007] [notice] mod\_fcgid: process 9646 going graceful shutdown, sending SIGTERM [Wed Oct 03 10:06:28 2007] [notice] mod\_fcgid: process 9645 going graceful shutdown, sending SIGTERM [Wed Oct 03 10:06:34 2007] [notice] mod\_fcgid: process /home/----/ studentlife/releases/20070716223737/public/dispatch.fcgi(9646) exit (communication error), get stop signal 15 [Wed Oct 03 10:06:34 2007] [notice] mod\_fcgid: process /home/----/ studentlife/releases/20070716223737/public/dispatch.fcgi(9645) exit (communication error), get stop signal 15 Now that the pages are cached, they load normally. Clear the cache or edit one of the pages, and occasionally fcgi will crash again. Anyone have any insight into why this might be happening? Thanks, Ryan ---

There might be a per-process memory limit on the FCGI processes. Honestly, though, I can’t say for sure. I haven’t used FCGI in a long time. Sean ---

AITOR - yeah, I’ve read every result in that google search. Most of those posts have to do with running Rails/Radiant on a shared host like Dreamhost. The rest of them say to use Mongrel. I’m trying to get the IT department to set up mod\_proxy so that I can use Mongrel instead of mod\_fcgi. I’ll let you know how it turns out.
