Duplicate IPs / Client Lockout


FileMaker Server



Operating system version

OS X Server 10.6.7

Description of the issue

We have two database files accessed from FM Go up to 50 clients and up to 10 FM. This problem occurs, however, even if there are very few (as few as 5) active clients using FM Go. When executing a script that changes to a particular layout, all connected FM Go users become locked. If they exit and try to reconnect, a duplicate IP appears in the admin console, but the users cannot get further than a partial display of the initial layout, after which spinning occurs for these clients.

The server continues to run scheduled backup scripts. But you cannot use the console to disconnect any clients, duplicates or otherwise. The way to restore the filemaker server is by restarting the host computer. Sometimes the host computer will not shut down normally and will have to be forced off with the power button.

We have recreated the databases from earlier versions that did not seem to exhibit this problem, but then the problem returned.

Steps to reproduce the problem

We can sometimes reproduce the problem by tapping a button executes a script that switches to a layout. We have replaced both the script and the layout. The problem has still reoccured.

Expected result

Normal use.

Actual result

All connected FM Go clients freeze.
Sometimes, connected FM Pro clients freeze.

Exact text of any error message(s) that appear

Spinning disc.

Configuration information

All iPads are running latest operating system and latest version if FM Go. Servers are running OS X Server 10.6.7. The servers are Mac Mini servers with 4 Gigs of ram and plenty of hard drive space. We have used a variety of hardware with the same results and have concluded this is not a hardware problem.


Rebooting. We have started designing replacement software, but would prefer to continue using FileMaker, which I have been using for more than 25 years. Any ideas or advice would be appreciated.
