I’m setting up a brand new second server for my Rails applications, and am having a problem with server load getting out of control. The machine is a quad core 2Ghz with 4G Ram and a single 500GB disk. This is a web/app server with no database. When I direct traffic to the server and its stable, the thing runs great - low Load for a few hundred Rails requests per minute. If I up the load (either more users show up, or I deploy with Capistrano), the Load level increases to 1-2, and then _never comes back down_. With enough traffic going to the server, the load sometimes gets out of control, slowly increasing until I direct the traffic back to my other server. I’m having real trouble diagnosing where the load is coming from. CPU usage is really low, disk peaks during deploy, but goes back down, network traffic isn’t huge. Anyone got any ideas on what I can try next? This is a brand new server, so there may be something broken or badly configured. ---

Have yo monitored the server with top/htop to find the offending processes? What is you stack in this server? What does the log say? – Aníbal Rojas > **[Home - Has Many Developers](https://hasmanydevelopers.com/)** > > We are the best choice for your building design and development > **[RUBYCORNER.COM](https://www.rubycorner.com/)** > > RUBYCORNER.COM - Contact us for any business inquiries [http://anibal.rojas.com.ve](http://anibal.rojas.com.ve) ---

I have been using atop, and it shows spikes in disk usage during deployment, then again after deployment (there’s a lot of cache on the machine, so I assume its being flushed there) The processes are not using any more CPU during this time, but the load is slowly going up, and response times are getting longer. CPU Wait Time isn’t going up either. The stack is: Ubuntu 7 Server, Nginx, Rails 2.02, Mongrel 1.1.4, MySQL 2.7 driver to a remote MySQL server. This is the same configuration as my server running Ok There’s nothing notable in any log I can find. I think there’s a hardware problem, but the disk diagnostics I ran came up clean. I’m having my server provider take a look. This server is clearly unacceptable - Quad Core, 4GB RAM can’t run 3 requests per second of my Rails app without the load going over 10 after a deploy ---

Should show a hight time for the DB in the production.log, looks like this is not the case (again acording to the information supplied by CRAZ8) CSI Server 😉 – Aníbal ---

Is your system swapping ? Are you running memcache on the server? What’s the location of the db that it connects to ? Is it local (same switch) ? vmstat -s (check ram usage) How many mongrel processes on the server ?
