Controllers not passed as a parameter causing an error

Hi!

I have an app that is already working on a shared host, but I need to run this on another server that was setup from scratch. Currently, the server has the following specs:

OS: ubuntu Apache 2 MySQL 5 Rails 2.3 (but I'm using 2.0/2.1) Ruby 1.8.6 FastCGI(mod_fcgid)

So far the application works fine but during the submitting of forms I sometimes get an error and on the log file was

The weird part here is I don't know, when and how it usually happens since most of the time it would work fine but sometimes it appears. before I thought it has something to do with my session expiration feature, but as I was checking it seems that this usually happens during the submitting of forms. Does anyone know the cause of this?

Actually this error causes problems on session after it happens.. I prove it since I cannot login after this happens. Also I usually use this command to fix this temporarily..

[sudo] killall -TERM dispatch.fcgi

EDIT: after some more testings, I found out that sometimes the controller and action parameters are not being passed and the controller that is being executed is the Application Controller. Does any one knows how this happens?

See on the database is there is any row with out id if not then pass id to controller by this :id = object.id

Thanks kannav for replying

I'm pretty sure that every row has an ID. I've been trying to look for more details on this error and I found out more updates on this one. One of these is that it happens randomly and this time not just on form submitting. An example of this is on the Ajax part generated by periodically_call_remote function on ruby that calls on a function that has nothing to do with the database. I did check the log files and found out that again it sends out only the authenticity_token where it suppose to send the controller and action also. Weird thing is I can't figure out how and when this happen. I also notice that this only occurs on POST requests only but that happens at a random events.

The bad thing about this is once the error occur, all the POST request causes the same error for all session users. That makes also logging-in on the application impossible. For me to make it work again, I usually kill all dispatch.fcgi process.

I just hope you or someone can help me figure out this problem since this one is urgent..:frowning:

Thanks, Aj

I did some checking on this and found out a line in vendor/rails/ action/pack/lib/action_controller/cgi_process.rb that goes like this

raw_post.force_encoding(Encoding::BINARY) if raw_post.respond_to? (:force_encoding)

I commented this out and the application seems to work now, but I'm not sure what this line is for.. Can someone tell me?

TIA!
