Unexpected 503 Errors after ~1 day of uptime
I recently deployed a RoR-powered questionnaire on LiteSpeed 2.2.1 standard and Mac OS X Server 10.4.7 and have been experiencing periodic (every day or so of uptime) 503 Errors despite very light site traffic.
When I first encountered this problem my max connections setting for Rails apps was 10 and I had a 60 sec. initial timeout so I bumped these to 30 and 120 sec. respectively. However, again after 1 day of uptime with light traffic the site began serving 503s. The Rails app was stilling running when I check in the web admin. Performing a 'graceful restart' allowed the web server to return to normal functioning.
stderr.log is filled with:
/opt/local/lib/ruby/site_ruby/1.8/powerpc-darwin8.7.0/lsapi.bundle: warning: already initialized constant ENV
fork() failed, please increase process limit: Resource temporarily unavailable
All that appears in the error log are 'file not found' entries for a folder that does not, in fact, exist (must be a configuration issue):
2006-10-16 14:55:24.550 [INFO] [22.214.171.124:57973-0#MyApp] File not found [/Library/WebServer/RailsDocuments/MyApp/public/run/]
The access log for the Rails app itself indicates nothing abnormal.
I did notice this line in the changelog for 2.2.2:
Fixed: Registered "env_copy" as a ruby global variable to prevent it from being garbage collected resulting in possible 503 error.
Could this be related to the issue I'm experiencing?
