MySQL has gone away
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?

Ezra....allow_concurrency = false?
In a previous email you wrote this:
Glad you''re getting some use out of the plugin ;) ActiveRecord does
have some issues with threading and concurrency that can sometimes
cause that error you are seeing. Open up your script/backgroundrb/
start file and comment out the following line:
ActiveRecord::Base.allow_concurrency = true
Make sure you do that up in your main app script folder

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:

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

postgres barfage revisted
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

radrails gone mad
Hi *,
I have been using radrails as an IDE for awhile now and we were getting
along just fine - but recently it has just gone totally postal?!??
I created a new rails app - when I click to expand the folders there is
no framework in place, just the root folder of the app.
To add insult to injury two weeks of work also just disapeered - I kid
you not just gone without any deletion on my part.

first i will say hello to everybody here, especially to Ezra
Zygmuntowicz!
I played a little bit with a dummy worker and so far everything worked
well.
But now i want to do real work in a worker but now i get that error[1].
It looks like that the constants configured in environment* configs are
not available to the worker

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,

Drb Connection error on multiple dispatch.fcgi ''s
Hi All,
I''m using Backgroundrb as a general purpose long-running-task back-end
(upload processing, email sending, etc), and it''s been a great solution.
However I''ve recently run into some some intermittent connection issues
that have me baffled. I''m running on apache2/fcgid and the problem
occurs in both devlopment and production mode. The problem seems to

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:

Production RAILS_ENV / DB Selection
Hey all,
I''m having some issues moving a project that incorporates Backgroundrb onto
a staging server... For some reason (surely of my own doing), my RailsBase
workers are insisting on using trying to access my development DB instead of
my "production" DB.
When I try to load a model object from within a worker, I get the following:

error message for record not found ?
I''m using backgroundrb for session management and deletion of visitor-entered information when a session is abandoned. The visitor can either click a button to end their session and remove their data, or backgroundrb will do it for them after 5 minutes of inactivity.
Everything''s working fine, I think. If the visitor explicitly logs out, then when the worker checks for their

How is Actionpack is not thread-safe? @@allow_concurrency?
Hi,
I found many references on the Web to the fact
that "Rails is not thread-safe".
However, I have not found an explanation _why_ it isn''t?
What happens if multiple requests are handled concurrently
by ActionPack?
Assuming that the code I execute in my controller methods
is thread safe, is this ok?
If not -- what happens?
The following makes it sound like the issue is

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?

:job_key acting weird?
Hi all
I''m experiencing something strange with a :job_key, it took me a very
long time to find out a worker wasn''t doing it''s job because of the
name of my job_key. The first one I tried was :make_kohier, and with
that name (and lot''s of other ones) I can''t get the worker to work. I
do get my key in return, but the job doesn''t start
