I have a backroundrb scheduled task that takes quite a long time to run. However it seems that the process is ending after only 2.5 minutes. My background.yml file: :schedules: :named_worker: :task_name: :trigger_args: 0 0 12 * * * * :data: input_data I have zero activity on the server when the process is running. (...
I'm using DRb within a Rails application to offload an expensive task outside the Rails process. Before initializing the client stub with DRbObject.new it is necessary to initialize the DRb service with DRb.start_service. Doing this in model or controller appears to leave threads in an uncertain state. When I exit mongrel it says: Reap...
It seems like due to the threading issue logger.warn (thats what I tested) doesn't generate any output? my code is similar to this: def deliver(args) logger.info "delivery start" thread_pool.defer(:deliver_deferred, args) logger.info "delivery end" end def deliver_deferred(args) logger.warn "whatsoever" end Any idea? ...
Hello, I have an application that checks a database every minute for any emails that are supposed to be sent out at that time. I was thinking about making this a rake task that would be run by a cron job every minute. Would there be a better solution to this?

Say, I have a worker that's set up to run every 15 minutes using the cron scheduling feature of backgroundrb. Then, say, if a single instance of the worker takes longer than 15 minutes to run, I don't want a second worker to be started in paraller by backgroundrb. How do I achieve that? ...
The problem: we have jobs that run from a few seconds to a few minutes in BackgroundRB from a Rails app. But, what happens when we deploy new code and restart BackgroundRB when it's performing a task? BackgroundRB does not seem to pick up any 'taken' tasks and I have not been able to find anything that can recover these tasks. Can anyo...
I'd like some thoughts on whether using fork{} to 'background' a process from a rails app is such a good idea or not... From what I gather fork{my_method; Process#setsid} does in fact do what it's supposed to do. 1) creates another processes with a different PID 2) doesn't interrupt the calling process (e.g. it continues w/o waiting f...

I have a BackgroundRb worker in charge of dispatching some emails. How should I tell this worker not to run during tests? Does the framework include some configuration parameter or stub worker I could use? MiddleMan.worker(:emails_worker).async_send_mails(:arg => {:emails => emails}) ...

What if your hosting use mongrel cluster and you have no access to it (except start/stop) One of solution i found on forums is code snippet in backgroundrb plugin with check for PID exist (if not exist start with exec or system) etc. Just your id...
