Why would my app give 504 errors when used on more than two machines?

More sanely.

Check the max number of sessions in the server and the sessions in your apps. If you have more than two sessions in your app and its running on two machines that will give a minimum of 6 sessions which is over the 5 sessions for the freebie server.

If there are two or less sessions in your app that would indicate in Tim's code somewhere (assuming you're using the free server with its 5 sessions).

Roy I don't use the EDB server as I don't need remote connections only
local file server connections. As for sessions I only use one session
component.

That's a bit worrying My reading of the error number in the manual makes me think its only applicable to c/s. Looking at the EDBEngine component it has LicencedSessions set to 4096 by default - difficult to exceed with two PC's unless you happen to be a total moron.

Have you possibly altered LicencedSessions accidentally?

Actually it is behaving just like the EDB VCL trial: "This version is
identical to the standard version of ElevateDB except that it only
allows up to 2 concurrent sessions per ElevateDB configuration."

I know I downloaded the full software and not the trial though.

Yikes that's it. I never changed this property or even knew about it.
All my apps are set to 2 LicencedSessions. I guess it held over from
when I used the trial. Thanks Roy!

Michael,

Yep, once that property is set EDB cannot just modify it automatically, so
you have to make sure that you set it to a higher value after switching from
the trial version.  It's not the greatest situation, but it's an improvement
over the nag dialogs.

Spoke too soon. I can't change this property. After trying to change
it, it reverts back to 2. I guess it thinks it is still the trial for
some reason. After uninstalling and reinstalling it defaults to 4096.
Maybe I didn't uninstall the trial properly.

That's usually the cause.
