backgroundrb not cleaning up tmp files?
I just had an interesting issue on a production system that has been
running nicely for about a year. There were approximately 10,000
backgroundrb temp files in the /tmp directory. It looks like
backgroundrb wasn''t cleaning them up.
I noticed it with the following error:
DRb::DRbConnError: drbunix:///tmp/backgroundrb.20015/

Exception when doing DRb remote calls from a BackgrounDRb worker
Hello,
I am trying to make DRb calls to a external server from a backgrounDRb
worker, but I''m getting always the next exception when I make the remote
call.

Stopping DRb after using BackgrounDRb::MiddleManDRbObject.init
Hi,
I''m having a problem where connections started through
BackgrounDRb::MiddleManDRbObject.init are not stopped, resulting in an
ever growing established connections between my Mongrels and remote
backgroundrbs
I added DRb.stop_service to my code executed after requests that init
MiddleManDRbObjects but that does not help.
Any ideas?
Thanks,

Yet Another Problem with BackgroundRB
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?

Connection to backgroundrb is lost when exiting action method
Hey.
I have a very annoying problem, and was wondering what is wrong.
Suppose I have backgroundrb running, and then I have an action in some
controller. In the action I define a worker. When leaving the action,
suddenly the connection to backgroundrb is lost:
DRb URI: druby://localhost:22222
Pid: 3976
Autostart...
done

Using BackgrounDRb to replace nested loops?
In response to my Rails Weenie post today[1], someone mentioned that

Weird DB Session error, "Mysql::Error: Lost connection to MySQL server during query"
I''ve discovered something really weird in rails 1.2.3 (It could be
fixed in 2.0? but I don''t know).
Recently I started getting the error "Mysql::Error: Lost connection to
MySQL server during query" in my application. It seemed like it had
popped up almost without relation to anything. There was a page in the
RoR wiki with possible solutions but none of them had worked

Noob needs help installing backgroundrb on Windows XP
Hey Guys,
In the readme for Backgroundrb it says that windows support has been
depcreated for this version, but then it goes on to mention how to use
it in Windows. So I''m not sure if it should be running on windows or
not, so I''ll ask anyway. Also, I''m new to ruby and I''m also new to
server administration, so I apologize if my questions are pretty

BackgrounDRb newbie stuck at first base. Fresh pair of eyes needed
Can''t believe I can''t see the problem here, but after a few hours
bashing my head on a brick wall, going to risk looking stupid by seeing
if anyone can point out my idiocy (that''s the worst thing about coding
on your own).
Trying to get BackgrounDRb to take over the scraping task which is
currently being done in a Rails controller. That''s not the problem at

BackgrounDRb background task runner and Application Wide Context Store
Friends-
I''m happy to annouce the first alpa release of BackgrounDRb. This is
a small framework for managing long running background tasks that
allows for ajax progress bars and more. It also serves as an
Application wide cache and context store for when you need something
like sessions but shared between users and multiple backend processes
like fcgi''s or mongrels.

''m having trouble with BackgrounDrb
Hi. I thought that BackgrounDrb was the perfect solution for my long
running report production tasks.
But I can''t seem to get anything useful back out of it.
I set up a simple test worker that just does
class TestWorker < BackgrounDRb::Rails
attr_reader :pupil
def do_work(args)
@progress=0
@pupil=Pupil.find(3)
sleep rand*10
@progress=100
end

Mutex::Synchronize with backgroundrb
I have a question concerning where to use the synchronize function. The
point of it is to put all of the code blacks passed to this function in
a queue. This make sure that code gets ran one at a time. This is
required when doing any kind of database activity in backgrondrb and
multiple threads. Otherwise I lose the connection to my database.
So here is my question:
Do I need to do:

How you want BackgrounDrb to behave
Hi,
Ok, As i promised.. I am working on new version of BackgrounDRB, which
is getting close and will be out soon. I need some feedback from you
guys. So, please reply back.
The code has changed significantly and its no longer using DRB. But I
will keep the name BackgroundRb. Ok, in new API, a worker looks like
this:
require "net/smtp"
require "guid"
