On Zed''s suggestion, I caught two new spinning mongrels and sent a SIGUSR2. The code appears to be stuck in read_multipart for both processes: # kill -USR2 6109 ** USR2 signal received. Thu Sep 21 14:55:39 EDT 2006: Reaping 1 threads for slow workers because of ''shutdown'' Thread #<Thread:0x419d7ce0 run> is too old, killing. Waiting for 1 requests to finish, could

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

Hey folks, I ran into a few people at RubyConf who were having 99% CPU issues. Please contact me if you meet the following criteria: 1. You are running a production site. 2. You are experiencing 99% CPU errors. 3. This is frequent enough that you cannot manage it. Thank you. Please contact me off-list about it. -- Zed A.

Howdy. I''m working on a RoR CMS and need cached pages to all be in public/cache rather than public [in order to set svn:ignore on all the files properly]. I can get page_cache_directory set correctly and the pages are cached in the right place but Mongrel isn''t serving them because it''s only looking for them in public. During development I know I can set -r public/cache

Hello Everyone, I just posted another pre-release of Mongrel that fixes a bug which caused Mongrel to claim it was getting parsing errors because the QUERY_STRINGs were too long. In actuality it was shift in the parser that made empty queries (/test?) become negative. This is fixed up now. Here''s the full list of changes: * It has a couple of fixes for win32, but I still have to

Hello, I''ve been using NFS for sharing files across a cluster of servers but I''ve had a lot of problems with that. I''m planning to move to MogileFS which seems to be more stable and more adapted to this usage (lots of user uploaded files). I wonder if someone has already worked on an integration of MogileFS into Mongrel (and Rails app) for serving the files ? If not, I

I''m going to make a change to how Mongrel is versioned to help out folks packaging it and tracking it as a pre-release. Previously I just did whatever was simplest, but now I''m going to do a slightly different approach. This is open for comment and suggestions. Here''s the new rules: 1) There are only official and pre-releases. This doesn''t change. 2) The

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

I''m spending today writing documentation. I''ll be updating quite a few documents, doing some edits, and adding some user contributed docs. If anyone has documentation suggestions, FAQ questions they''d like included, or things they think are old and stale, then let me know. Swing by the Lingr room: http://www.lingr.com/room/3yXhqKbfPy8 And drop me a line if you want

Hi Everyone, Just want to get out another ping on the Mongrel pre-release saga. I''ve updated a bunch of the documentation to include documents people have donated and to beef up the FAQ for most of the questions people have asked over the past month.

Hi ! My mongrel just starting spitting out these nice lines: The error occured while evaluating nil.accept. TELL ZED HE''S A MORON. !!!!!! UNHANDLED EXCEPTION! You have a nil object when you didn''t expect it! Not sure what happened or why, but just FYI: Zed, you are a moron :-) Happy holidays! Gitte Wange

IE6 happily sends unsafe* characters unencoded if you''ve typed them into the URL bar of your IE6 window. This could happen if you copy & paste a URL from an email or web page. Mongrel doesn''t seem to handle these properly. In 0.3.13.3 it would print out something like: Sun Oct 15 23:05:38 CST 2006: BAD CLIENT (192.168.1.2): Invalid HTTP format, parsing fails. 0.3.13.5

Time for some all time pimpage folks. Me and Matt Pelletier wrote a small PDF book on Mongrel entitled: "Mongrel: Serving, Deploying, and Extending Your Ruby Applications" since we really wanted you to know what it was about. It''s published by Addison Wesley Professional, has just over 100 pages of goodness, and is available for $14.99 at: http://safari.oreilly.com/0321483502

Hi, Whenever I restart mongrel on my production server, the first request in my browser always fails, I get this error: Processing Base#index (for 83.xx.xx.xx at 2006-09-03 16:08:47) [GET] Session ID: f1918346d193e19a70c3230286e5ce1a Parameters: {} TypeError (superclass mismatch for class Stats): /app/models/stats.rb:1 stats.rb:1 just contains a normal A/R line: class Stats <

Hi One of the two mongrel processes has died in the middle of the night four times in the past 9 days, and I need help debugging this. Each time the symptoms are the same: * Each time I can restart the process via cap -a restart_app. * Before the restart, there is nothing unusual in production.log or mongrel.log. * During the restart, about 100 repetitions of an error message are generated in

Hi everybody, I just suscribe to the list because I have a problem using mongrel and mongrel_cluster... I setup a server (debian unstable wich provide apache 2.2.3 as a pakage) but I have an error when I try to access my application : ERROR 403 : Forbidden, You don''t have permission to access / on this server.

Hi, I just gave Mongrel a try on my Rails app. After running ''mongrel_rails start'' everything seems fine. Yet, when I start a request I get the following error message on the console: ERROR: You have a nil object when you didn''t expect it! The error occured while evaluating nil.readpartial That''s it. The application works fine with Webrick and

Hello Minions! It''s *finally* here. Mongrel 1.0 RC1 for everyone to test, even the win32 folks. I managed to get everything to build on windows, including fastthread, and even cleaned up the "releases source":http://mongrel.rubyforge.org/releases/ so that it should install cleaner. Win32 will have to try and report problems, as it seems rubygems is real finicky on win32.
