I’m trying to create a win32-service (ruby script with Rails environment) utilizing the Daemon class and it currently prematurely exits when it encounters a method of mine that calls a delivery via ActionMailer. Here is the process: Windows Service (Ruby script Daemon class) | v MyModel.save (from within the Ruby script via requiring the Rails environment) | v after\_create :deliver\_notification This causes my Daemon to exit. Has anyone tried anything similar? I’ve tried breaking the MyModel.save off onto another thread with no luck. I don’t know if the problem is the time required to deliver the message or if it’s because ActionMailer uses its own Daemon. Anyone have any thoughts? ---

Just an update, the exception I am capturing is a “Bad file descriptor” exception. The actionmailer model and method work well outside the windows service. ---

Permissions problem maybe? I have a vague association in my mind between that error and server not being accessible… What credentials does your service run under? Is it an account w/network permissions? ---

From the command line in an interactive session? That’s != the environment you get when you’re running from a service… If you haven’t already, just for a goof, temporarily have the service run under your domain credentials & see if it makes a difference. ---

Sadly that didn’t make a difference. I even tried to log out and back in again, which still caused the same exception to be logged. Can a daemon such as ActionMailer’s delivery methods be called from within another daemon (win32-service)? Vic. ---

I have what seems to be a solution. The problem was unrelated to ActionMailer. In reality the problem was occurring because of a few constants that were declared in multiple places. When MyModel re-declared these constants this error (Bad File Descriptor) would be being thrown. ---

Is it an account > w/network permissions? Thanks for replying! I seem to have full permissions from the command line and everything else works from the service except the mailer. I don’t forward any credentials to the mailer concerning my actual login either.
