similar to: Preventing Mongrel/Mysql Errno::EPIPE exceptions

Hi everyone, I have been trying to solve this problem for quite some time now and I really don''t have any further clue to investigate. I am running a mongrel_cluster 1.0.5-2 (mongrel verison : 1.1.5-5) on a ubuntu box with apache2 2.2.12-1ubuntu2.1 I have 4 different apps on the same box and each app has two mongrel instances. After a short period of time ( < 2 hours ) some of the

I know this question gets asked a lot but I can''t seem to find the answer when I search through the mailing list. First off here''s my set up. Cent OS 4.3 Apache 2.0 Fast CGI 2.4.0 Rails 1.1 Mysql 5.0 The app starts up fine, but every morning it refuses to start and gives me the dreaded Application error untill I reload Apache. I thought my database was timing out so I added

Greetings, I need some help... please be gentle :-) MY SETUP: Solaris-X86, ruby-1.8.4, Apache-2.2.0, Mongrel-0.3.13.4, MySql-4.1.10a I am using the typical setup with apache proxying request to mongrel with mod_proxy_balancer. Currently, I am only running a single instance of mongrel behind the proxy. I am also using the following gems with this app: capistrano (1.2.0) daemons (1.0.2)

Hi, I have had trouble with mongrel freezing after a period of inactivity. Following the advice from the mongrel FAQ, I added: ActiveRecord::Base.verification_timeout = 14400 to my environment.rb file. Unfortunately, that registered a mongrel error: "uninitialized constant ActiveRecord (NameError)" How do I overcome this one? I tried: require ActiveRecord::Base but that registered

My app consists of receiving emails with image attachments from its users so I have been employing the MMS2R gem and Fetcher. Every 60 seconds the app goes to the email server to fetch emails. Under Rails 2.1.1 things worked fine - when I received an email, the email was fetched, parsed and saved to the database. However I needed to upgrade to Rails 2.2.2 for unrelated reasons and now I get the

Recently I started noticing that after running for a while puppetmaster would freeze after a client called `freshness` which would eventually result in the client getting a timeout and the client dyeing. I tracked the freeze down to the call to ActiveRecord::Base.verify_active_connections! in rails.rb on line 26. After scouring the nets I finally found:

This isnt totally a rails question; I am using ActiveRecord for storing some simple values into a database. My problem; I keep gettign MySQL Errors. On the Win32 machine it was off and on. Now on the linux machine (ubuntu) I can'' t connect at all. I have all the password settings correct. My only thought, I am working with Threads and thought that might cause the issue, but I

Hi, in a production environment we are running into "MySQL server has gone away" errors (see below) when we call rebuild_index in aaf. This happens sporadically. Any suggestions for what might be wrong or workarounds? I guess we try a reconnect before we call rebuild_index?

Hi I posted this to the Ruby on Rails Talk group but I thought I''d post it here too as it''s probably a more appropriate group. Hope this is ok. I''m running a 2-instance Mongrel cluster behind Apache 2.2.4 with Rails 1.2.3. If no requests are received by the application for several hours (this usually happens overnight) then Mongrel stops responding and no requests are

Hi! I got a class named EinsatzFilter which I serialized to session. Before saving to session it works afterwards I keep getting the message: "undefined method `to_s'' for #<Person:0x38c6ab8>". "Person" is a from ActiveRecord::Base inherited class. Code: class EinsatzFilter include ApplicationHelper attr_reader :personen, :monat, :projekte, :kunde

See the graph at http://tinyurl.com/35rnx4 For some time, I''ve been watching the three combinations ruby + rails, ruby + developer, java + hibernate + tomcat using the www.indeed.com job-trend grapher. They have (after a long climb), finally reached parity. Of course, you can pick different combinations and get entirely different results. -- Mike Berrow -- Posted via

Hi, We are running a Rails application in development mode. Intermittenly we get an error on some pages, saying : undefine class/module User. If we refresh the page, the error goes away and we see the html correctly rendered. User is a model defined in the models directory and has been listed in application.rb as model :user. I am suprised by the fact that this happens only occasionally. Can

Hi, I have Apache (2.2) setup to proxy requests through to Mongrel (0.3.12.4) for a Rails (1.1.2) application (on ruby 1.8.4). The setup is great, but I''m experiencing some nightly failures. I thought I''d post here before digging in too deeply, but it looks like Rails is going into lala land and Mongrel can''t recover... Seems like everything gets all backed up in

i am using the following comman to fire up mongrel: [sergio@vb_workstation chatlogger]$ mongrel_rails start -d -p 8088 ** You have sendfile installed, will use that to serve files. and everything works fine until some point at night.. i think it is pooping out some time in the middle of the night.. if i try to hit the app in the morning, it just stalls out.. if i restart it, it''s

Hi I''m running a 2-instance Mongrel cluster behind Apache 2.2.4 with Rails 1.2.3. If no requests are received by the application for several hours (this usually happens overnight) then Mongrel stops responding and no requests are detected by Rails (at least nothing is in the Rails log). Nothing untoward is in the Mongrel log. If you try and visit the application, the request times out

Hi, I''m trying to make a simple shopping cart, where I want to maintain state when a use logs in from different location. Consider the following : 1. ''foo'' logs in from home pc and add ''bar'' item to the cart. 2. ''foo'' goes to office and logs in from office PC. 3. Now I want only one session for ''foo'', so that when

Hello, I am running mongrel 1.1 in production mode behind a lighttpd with mod_proxy. At first everything works fine, however, after a few days, the mongrel servers stop answering at all, even if I try to connect to them directly. I have checked logs but there is no sign of anything at all, and even when there was not a single request for a few days, it did freeze, and that on repeated occasions.

Dear ALL, I saw this in article from mongrel faq, Q: Mongrel stops working if it''s left alone for a long time. If you find that Mongrel stops working after a long idle time and you''re using MySQL then you''re hitting a bug in the MySQL driver that doesn''t properly timeout connections. What happens is the MySQL *server* side of the connection times out and

Would anyone happen to have some advise for this? I have a script that runs for months at a time. On one box, I can do this without issue, on another it disconnects after a day. I''ve been trying various solutions, but since it takes a day to test any idea, it''s been very slow going. I''ve tried Issuing a reconnect command, after any ActiveRecord error. Which

Hi all, I''ve been having problems with the apache 2.2-mod_proxy_balancer- mongrel setup.
