By default, any ColdBox app has a lock timeout of 30 seconds for their requests. If longer running processes occur in which they do not give the lock away (for whatever reason it is) there could be a chance of the request to timeout and throw and error. Therefore, you might be interested in maybe increasing it on high availability applications in order to allow longer running processes to finish. In order to tweak this setting, you should open your Application's Application.cfc file.
* This only works on Application.cfc's that use inheritance. Non-inheritance Application.cfc will have to wait for ColdBox 3.0 or manually change this in the main coldbox.cfcOnce inside the file, locate the following:
And add the following snippet:
That's it! You use the setTimeout() method and pass in an integer that denotes the number of seconds to wait for a lock. Now, most of the time, if you have processes taking longer than 30-45 seconds, that to me is a red-flag going up. You should seriously revise your code and processes of why you want processes running for so long.

One may not want processes running for too long on public facing sites.
However, if you have private management type pages that may run for a long time but they work well otherwise, what's your recommendation for including those in an application?
I tested a long running page and it caused a timeout error on the public facing part of the site. Is the only option to move those long running pages into their own so that it doesn't interfere with the public side?
Thank you,

So, I looked into the framework code and found that my timeout error was occurring because, in a development environment, I am everything with each request.
So the long running request caused the public side request to fail because it couldn't get a lock in the of coldbox.cfc.
That said, I changed to a environment (doesn't reload everything on every request) and the long running request did not bring down the public facing side.
I think I should be ok leaving these long running pages as part of the same app as the issue does not happen with real production settings. If you'd advise otherwise, please let me know.

Yes, auto reload puts a lot of stress on the application because every request has to do exclusive locking just to make sure the app get's reloaded.
Definitely use it for development only if possible. Lock timeouts and request timeouts are two different settings.
