I chose to instantiate a vhost from one of my VH templates. I did this because I wanted setup for a rails site using the external app. The reason I did this is because I wanted to test the "Memory Hard & Soft Limit" settings. However, I keep getting a 503 error. I did try increasing the Memory limits up to 500m like the documents suggests. I started out by removing my rails context. Next I added an "External App" for the LiteSpeed API My settings look like this: Name rubyLSAPI Address uds://tmp/lshttpd/rubyrailslsapi.sock Notes Not Set Max Connections 2 Environment RAILS_ENV=production LSAPI_CHILDREN=10 Initial Request Timeout (secs) 1M Retry Timeout (secs) 0 Persistent Connection Not Set Connection Keepalive Timeout -1 Response Buffering No Auto Start Not Set Command $VH_ROOT/public/dispatch.lsapi Back Log Not Set Instances 2 Run On Start Up Not Set Max Idle Time 60 Priority 1 Memory Soft Limit (bytes) 100M Memory Hard Limit (bytes) 200M Process Soft Limit 100 Process Hard Limit 200 My contexts looks like this: URI / LSAPI App [VHost Level]: easybutton.us.rubyLSAPI Notes Not Set Extra Headers Not Set Allow Override Not Set Realm Not Set Authentication Name Not Set Required Not Set Access Allowed Not Set Access Denied Not Set Authorizer Not Set Add Default Charset Off Judging by what I read in the Step by Step,, these settings should work. Any red flags you see here guys?
