Hi Everyone, There''s quite a few of you who have contacted me about Mongrel suddenly stopping. After a lot of investigation, I found that the common thread between all of you is memcache and Eric Hodel''s memcache-client. People who were running this combination would have intermittent pauses and investigating the stalled mongrels showed that memcache-client was waiting for

Hi all, I''m getting a strange, intermittent Thread deadlock in production: deadlock 0x2a988d7008: sleep:F(3) - /opt/ruby/default/lib/ruby/gems/1.8/gems/mongrel-1.0.1/lib/mongrel.rb:723 CPU usage spikes to a full core and Apache 502''s on requests that got handed to that particular listener each time. I tried attaching with gdb, and gdb twisted itself into a knot. Anyone have

Hi, I''m using mongrel-0.3.13.3 with memcache-client-1.0.3 for storing sessions. It was working fine with actionpack-1.12.0, but when I upgraded to actionpack-1.12.3, I started getting a "can''t convert String into Hash" error from memcache.rb from memcache-client. I was able to fix it by changing the way the MemCache object was created in

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hey, I''ve been using Mongrel for quite some time now but I ran into an issue that threw me back to lighttpd + fastcgi. The application in question was running fine in the production environment with SQLSessionStore and using a mongrel cluster behind a load balancer. However, by switching to a MemcacheSessionStore (using either

Greetings, I posted this not on the Rails mailing list and didn''t get a definitive response so I thought I''d post it here, since I figure lots of you are using mongrel with Rails apps. Any suggestions would be greatly appreciated. I''ve been using file-based fragment caching and DB-based session caching quite extensively. I decided to try out memcached for both to

Hi, I was having problem with disappearing sessions when storing them in memcache and when runnning as mongrel cluster in production environment. I''ve created a patch and it seems it''s now okay. A message to rails-core including the link to patch <http://dev.rubyonrails.org/ticket/9823> can be found in the group here:

Hello Zed, I was just wondering if there were any roadmap/changes coming for Mongrel in the future. Are there any plans to put the attachment parsing code back in, or just anything else to be on the lookout for? Honestly everything''s been working fine for me, so I shouldn''t care, but I''m one of those guys who loves new toys every few months. Thanks for making my job

wondering if anyone watching can make sense of this, I''m try to work the memcache_client into my app, but every time it tries to read from memcache I get a Marshall error that the AR classes are not defined. But it''s more vexing than that, as the error does not occur within the console. From a console everything works as expected, but when running in the app it fails.

The Problem ----------- We have been getting a "undefined class/module" error on 2 of our 6 app servers in one testbed. Same sourcecode, same installs (systemimager and an isconf style configuration management harness), same binaries. Identical everything. Pound + mongrel + memcached + postgres (pgcluster). The odd bit here is that our "dev" and "prod" pairs had

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

It would be an interesting topic. I bet there are quite a few. I just released one that 1/2 runs on Mongrel. http://direxionfunds.com It was released before it was _quite_ ready, but the last of the content is getting inserted today. I am still waffling on how I will leave it running longterm. Right now it uses a slightly modified version of the Mongrel http parser with EventMachine to front

Hi, I am experiencing an error in the mongrel_rails script on a pc under cygwin/mongrel/rails.

I just created a test rails app, and am having very wierd issues with mongrel cluster. Here''s what I''m doing: rails test sudo chown -R mongrel:mongrel test cd test sudo mongrel_rails \ cluster::configure -e production \ -p 8000 -N 3 -a 127.0.0.1 --user mongrel \ --group mongrel It correctly writes the mongrel_cluster.yml file to the config directory. Now,

Hello All, I''m putting out a quick half-release because there''s some work on the MIME types I''ve included that needs to be done by all of you. Read at the end to understand your role in what you started. This release features two major capitulations on Mongrel''s stance of not being a full web server. The first is Mongrel now sports a YAML file with 739 MIME

In our app we''ve a number of singleton ruby classes that cache static data in hashes, things like string values, system config params, etc). In a webbrick environment this works ok, but we find in production we have a problem because we have 4 caches, one for each mongrel instance. This also isn''t a BIG problem, but our cache.reload() methods are kinda useless now, because we

Is there some kind of caching of session data in mongrel? What is the best way to get mongrel servers within a cluster to always keep their sessions synced? -- Jared Brown jaredbrown at gmail.com (765) 409-0875 7001 Central Ave Indianapolis, IN 46220 -------------- next part -------------- An HTML attachment was scrubbed...

I''m in the process of setting up a mongrel cluster at the moment, and I''m running into a bit of an issue. Even worse is that I''m not sure whether this is a mongrel thing, or an Apache thing. While I''m inclined to think that this might be a balancer thing, I decided there was a higher chance hearing back from mongrel-users than from apache-users, so I''d

And now it''s time for yet another Mongrel release. Mongrel is a small fast HTTP library written in (partly) Ruby. It is intended to be used by web app framework authors to make their applications fast and deployable without resorting to SCGI/FastCGI trickery. Mongrel is tested to work on Linux and Mac OS X (with more reports welcome). You''ll need a full compiler to

Hi all, I''m using Boxroom (http://boxroom.rubyforge.org/) and trying to get upload progress working. I''ve also been testing the sample code at http://itblog.mcgeecorp.com/2007/5/15/mongrel-upload-progress-demo/. I run a Mongrel cluster, and so am using drb (as per http://mongrel.rubyforge.org/docs/upload_progress.html). Starting up rails, I get lots of useful-sounding output:
