similar to: loading C extension in worker causes bus error on OS X only

I''ve been trying unsuccessfully for the better part of today to write a worker that can use by ActiveRecord model classes. The bizarre thing is that worker just stops at the point accessing the database connection. An exception isn''t raising, it just dies. My worker class is below, I''ve interspersed log messages throughout to try to determine where it is dying. =====

Hi! My cron-based worker is being indeed invoked by backgroundRB at correct times. But... After several runs it can no longer find DB columns! The same query, which was running OK an hour ago starts to throw MySQL error about unkown column in where clause. If I restart backgroundrb it works for some time but stops working after several invocations. Has anyone epxerienced the similar beahviour?

I''ve been troubleshooting this problem for several hours now and haven''t been able to figure out what''s wrong. I have two boxes, dev and prod, both are identical except that prod uses Ruby 1.8.5 and dev uses 1.8.4. Both are running Slave 1.2.0, Daemons 1.0.5, and Backroundrb 0.2.1. The behavior I''m seeing is this. When I first start Backgroundrb, this is what

Hi all, We use mongrel behind apache (using mod_proxy_balancer) to run an internal app for our business. Lately we''ve been seeing frequent errors from some of our mongrel processes. [Sun Dec 16 08:48:47 2007] [error] [client <CLIENT1>] (70007)The timeout specified has expired: proxy: error reading status line from remote server 127.0.0.1, referer:

Hi, I''m using backgroundrb 0.2.1 in a production environment and for most parts I''m very happy. We are using it to do some heavy video editing on the server side and it works great except that under, what seems heavy load the below problem happens intermittently. The problem has only happened 5 times out of over 500 runs by our backgroundrb worker. This is the code in our

Hi, I have backgroundrb running to decouple the execution of massive business logic from an ActionWebservice request. The service is designed to take some configuration parameters and fire a lot of background workers to do the requested work. Due to performance reasons I want to limit the number of workers to a maximum number of 30. But when I start a configuration that requires for example

I have been facing this damn ugly issue since quite sometime. So this worker reads RSS feed from Yahoo news and stores it in a DB. The worker is scheduled to run at every 40 minutes and my background_schedules.yml looks like this: feed_worker: :class: :feed_worker :job_key: :feed_worker_key :worker_method: :do_work :trigger_args: :start: <%= Time.now + 5 %>

Hi! I''ve just a created a really simple rails scheduled worker for backgroundrb to start playing with : class SessionCleanerWorker < BackgrounDRb::Worker::RailsBase def do_work(args) logger.info "SessionCleaner> started" CGI::Session::ActiveRecordStore::Session.destroy_all( [''updated_at <?'', 120.minutes.ago] )

Hi gang, Thanks to other help I''ve gotten on this list, I''ve got backgroundrb up and running using postgres alongside my rails app. I''ve designed the system to have several eternally-running workers that periodically poll the database to see if there''s any work for them to do, and set things up in the config file to make them restart quickly if any of them

I''ve got some workers that I want to have running all the time. Right now I''m just launching them manually, by requesting a special page in my rails app that includes lines like: MiddleMan.new_worker(:class=> :receiver, :job_key=>:r, :args=>{:sleep_time=>10}) This strikes me as a really weak way to fire up my workers. I basically want to automate things so

Hello - I am observing that calls to MiddleMan.worker return only after the worker has completed its work. This puzzles me, and I presume that I am doing something wrong. Can anyone make suggestions? Snippets from my code are: class ReportController < SecurityController ... def create_xml_report(report,start_time) constraints = get_constraints(report,start_time,false)

Hi, I am trying to limit the number of worker threads running at the same time. Adding ":poolsize: 2" to backgroundrb.yml or starting backgroundrb server like this script/backgroundrb start -- -s 2 does not seem to help. I can still create more than 2 worker threads from a rails app. I tried this on ubuntu dapper - ruby 1.8.4 - backgroundrb 0.2.1 as well as

First of all, I''d like to do what I''ve seen several others here do: thank Ezra and any other contributors for producing a really great plugin. Even though I''m having some minor problems, this is all so approachable and easy to work with and dig into... I hate to think of the hoops you''d need to jump through (both as creator of such a system and as a user) to

I''m at a loss to explain a very strange error I''m getting. This seems to happen on our production system where we have a backgroundrb server sharing a host with a Rails app running on Mongrel. The first one or two, occasionally three, calls to a worker (direct MiddleMan calls from Rails, not scheduled) succeed, but afterwards, the server fails to initialize new workers.

What does the method query_all_workers() do? There is no documentation on what this method returns (1.0.1 version). Orion -------------- next part -------------- An HTML attachment was scrubbed... URL: http://rubyforge.org/pipermail/backgroundrb-devel/attachments/20080118/9f9b8112/attachment.html

Hi Folks, I have been working to fix BackgrounDRb memory usage as such. Ruby1.8 GC isn''t fork friendly and it seems to use a lot of memory because when you fork, it sets a bit in all the objects in global scope which causes OS to all pages in child process. A classic solution is to use fork and exec, rather than just fork. Its working and pretty stable, but you loose ability to pass

I'm working with genotype data in a frequency table: > a=matrix(1:16, nrow=4) > rownames(a)=c("AA","AT","TA","TT") > a [,1] [,2] [,3] [,4] AA 1 5 9 13 AT 2 6 10 14 TA 3 7 11 15 TT 4 8 12 16 'AT' and 'TA' are essentially the same, and I'd like to combine (add) the rows to reflect

Hello all, I''m using BackgroundRb 0.2.0 (standalone) and in the do_work method of my worker, I''m working with objects from my Rails application. So in my config/backgroundrb.yml file, I added this line: :load_rails: true I think my worker isn''t doing what I want him to do. So I opened the console and read these error lines: # ruby script/backgroundrb console

Hi I just installed the gmodels package and the installation was successful but when I was trying to load the library I got an error (see below).
