Filemaker Server 13 Hangs when adding or modifying fields in schema
Operating system version
Windows Server 2008 R2 (Windows Hyper V Environment)
Description of the issue
Ever since we upgraded from FM/FMS12 to 13 whenever I make any field changes (in any of my solution files) as soon as filemaker starts to update the database records after committing the change it hangs and my screen goes white. All clients then freeze and the only way to remedy this is to forcefully disconnect all clients and try to close all files but this doesn't work and the Filemaker server seems hung. I then have to restart the server. After the server is rebooted and the files are back up the field change is present. We have monitored the server during this hang and don't see any noticeable performance issues. This Virtual machine has plenty of resources and as I said this never happened with FMS 12. On average there are about 25 active users at any one time when this happens. I have noticed that If there are less than 9 or so users the problem does not happen.
Steps to reproduce the problem
With many users connected try adding a new field to an existing file then upon clicking OK to close the field dialog window filemaker 13 client will hang.
