similar to: Determining ideal number of Mongrels for an app?

Z-Man, DHH recently said: "And [_why''s] latest work on sandbox looks stellar. Making it drop-dead easy to run multiple Rails applications in the same Mongrel process without conflicts. Thumbs up to both him and Matz for getting Sandbox on track for inclusion with the next Ruby release." Does that mean what I think it means - that one or more Mongrel processes may one day be

Lets say you have a site that is serving, oh, around 100k unique visitors a day (plain ole'' browser requests) - plus probably ~ 40k uniques to feeds. Assume this site is 90% read like most of the web, so the traffic looks like your typical news or portal site. There are two web boxes behind a hardware load balancer, each doing apache 2.2.3 -> mongrel_proxy_balancer -> mongrel

The company I work for is launching a new web site tomorrow. News of our launch will be published in major publications throughout the week so I want to make sure we are prepared for the load. Production Environment: HP Proliant server w/ 8GB RAM and dual AMD64 Opterons Memcache is used as the session and fragment store (512MB for it) MySQL is running on a seperate server in the same rack We use

I played around with this some more and when I changed line 142 of /opt/local/lib/ruby/gems/1.8/gems/mongrel-0.3.13.4/bin/mongrel_rails from "exec cmd" to "system cmd" Mongrel has successfully restarted every time I''ve tried ("mongrel_rails restart"). Hell if I know why exec doesn''t work -- googling on "exec Operation not supported ruby"

Most of my machines have apache+mongrel running but the mongrels are using the localhost. In my production environment, I have 4 boxes. I have setup 2 http servers ( apache 2.2.4 ) and 2 app servers. They are currently using lighttpd+fastcgi. Which I am changing this week. I want to get advice from you guys before I actually do this since this is my production env. I have installed apache on the

I''m trying to do some initial benchmarking of our setup, mainly just to establish baselines. I''m essentially using the process Zed outlines in a previous message: http://rubyforge.org/pipermail/mongrel-users/2006-May/000200.html What I''m running into is that Mongrel appears only half as fast as Apache when serving a small static HTML file. If I then add in Apache with

Hi list, I have tried to reach Bradley (author of mongrel_cluster) by mail, but have not gotten a response. So I''ll try trough this channel: I have ''developed''[1] a small extension to mongrel_cluster that allows selective restart of any one listener in a configuration that contains more than one listener by using a command like mongrel_rails

Hello Mongrels around the world! Been thinking a way to unify the issue I described in the subject. For those who aren''t aware, mongrel (actually, mongrel_rails) only generate the log file if daemonize was used (-d) That means no log file under windows, due his lack of fork/daemonization capabilities. Now, users that need to run mongrel on windows cannot report and fill the empty

I''m using a cluster of mongrels behind an apache 1.3 proxy pass. I''ve been passing the request to pen, which in turn balances the cluster of mongrels. Now, I''d like to be able to use a different server to send the static files created by the rails application, so I tried to replace pen with nginx. Everything seems to work fine except the environment variable REMOTE_ADDR.

Configuration: (2) Dual Core Opterons 8GB RAM Apache used to balance 40 mongrel instances We receive Application 500 Errors. Nothing suspect appears in the log, so we are at a lost as to what to do next. Any advice would be welcome and/or an explanation of what types of things cause Application 500 Errors in mongrel. Thanks! - Jared Brown -------------- next part -------------- An HTML

Calling All Mongrel Minions! I wanna have some fun and would like this as a Christmas present. The site http://www.workingwithrails.com/ has this lame popularity system that''s kind of irking some of the main Ruby contributors. I think it''s kind of funny, but would like to demonstrate what an army of motivated people can do to these kinds of popularity contests. So, as a

Hi all, Tried out the mongrel upload progress plugin with Drb and it works great on my OSX development box, but when putting it into production (Ubuntu Dapper), uploads complete but the app isn''t returning any values for upload progress, and uploads are not showing up in the queue when running upload_client.rb. Before anyone asks, yes, I''m running both the mongrel instances and

I have Mongrel Cluster setup with Apache a mod_proxy_balancer. I''ve seen (from time to time) mongrel instances become non-responsive. Is there anyway to configure the balancer so that it "knows" which processes are no longer good and stops trying to use them? _______________________________________________________ The FREE service that prevents junk email

We have a site that is running Mongrel and is down. Below is the Mongrel log file information. The server is a Linux server with 2gb of RAM. EV1 (hosting site) says that since this is a Linux server that the RAM is cached and that there is plenty of free memory available. Can anyone make sense of this error and have some suggestion of options that I may take to correct this issue and get

With Mongrel 0.3.18, I have not seen a single one of the hangs that I have been grousing about for the past N weeks. Thanks MenTaLguY and Zed! Q: Mongrel loads fastthread, Mongrel loads Rails, Rails loads OCI8, OCI8 requires ''thread''. That means OCI8 is using fastthread too, right? Steve

It appears that part of the problem could be that when logger rolls over the mongrel log file. There is a mutex synchronization issue where the various mongrel instances all try to write to the new log file and block each other. This keeps them in a continual Application 500 Error state. Has anyone run into this problem? With log rotation turned off the problem does not appear. - Jared Brown

Hi We''re running mongrel on CentOS 4.2 with Apache httpd 2.2 mod_proxy_balancer, mongrel_cluster-0.2.0, Rails 1.1.6, Ruby 1.8.4, Pg 8.1.4 backend. We are on the verge of going live with our site and I am stress testing the server. What we are seeing is under heavy loads, our mongrels will seg fault and die one by one. Following the advice in a previous thread (http://www.mail-

First off: Our clusters are LVS balanced Apache 2.2.3 + mod_proxy_balancer + gem mongrel 0.3.13.3 / mongrel_cluster 0.2 + memcached / gem memcache_client + gem rails 1.1.6 on debian boxen, and a pgcluster backend. On 2 of our deployed clusters, we are getting the "spinning mongrel" problem. As the clusters are very low volume right now, it takes days to collect a spinner, making it

I''m a bit surprised I can''t find anything about this in the mailing list archives. Basically since Mongrel 1.0.1 I''ve had Mongrels fall asleep without any real cause. A deep sleep, actually more like a coma. The mongrel in question (I''m using a cluster of three) can not be revived. A cluster::stop, then cluster::start is nessesary. A ::restart would not

Hey all, First off, thanks to Rick Olson and whoever else was involved with this plugin... It''s been amazingly easy to implement. I''ve got a question about the path_info parameter, though... It seems that unless the request PATH_INFO exactly matches the path_info passed in to the plugin at inclusion, it won''t actually trigger Add and add the upload to the list of
