Hello, I run a number of Django servers and every now and then we get an error in our logs stating something like:
[Thu Apr 08 17:10:07 2010] [error] [client XXXX] Premature end of script headers: upro_production.wsgi, referer: http://coursefinder.uprogps.com/coursefinder/upro/device/XXXX/ These errors are not accompanied by Segmentation faults in the main error.log and are not associated with us gracefully restarting apache. All our servers have nginx proxying to apache and all our static content is served by nginx. We experience this error across two sites: www.xterra.com and coursefinder.uprogps.com. Below are some stats: == Coursefinder == http://coursefinder.uprogps.com/ Django 1.0.4 500 max requests 3 processes 20 threads === Past 4 Days === 289 Premature end of script headers errors. Many not related to downloading a course ~ 72 Errors a day 7249041 Requests 1 Error for every 25083 Requests == Xterra == http://www.xterrawetsuits.com/ Django 1.1.1 500 max requests 2 processes 10 threads === Past 4 days === 22 Premature end of script headers ~ 5 errors a day 810000 Requests 1 Error for every 36818 Requests == Dcshoes == http://www.dcshoes.com/ Django 1.0.2 5 Sites Each configured with: 500 max requests 4 Processes 1 Thread No errors === Past 4 days === 473559 Requests Because dcshoes.com doesn't experience this problem and only has 1 thread per process, I am beginning to think that this is a threading issue. Supposedly Django 1.0.3 and later is thread safe. -- You received this message because you are subscribed to the Google Groups "modwsgi" group. To post to this group, send email to [email protected].
