Product and version: FileMaker Pro 16.0.2, FileMaker Server 16.0.2
OS and version: macOS 10.12.6 for client with FileMaker Pro, Mac OS X 10.11.6 for FMS
Hardware: FMP on Late 2014 MacBook Pro; FMS on 2009 Mac Pro
A script was invoked that does an Insert into Container via a calculated path variable. The file being inserted was an XML file of about 18 MB. At the same time the insert was happening there was a backup script that was running on the server. The insertion never completed, FileMaker Pro just sat for 30 minutes with the "Inserting..." modal dialog box. I had to force-quit FileMaker Pro. Both the FMP and FMS machines were on the same 1000T local network.
How to replicate
Would have to try inserting into a container while a backup script was backing up the database being inserted into.
Workaround (if any)
After force-quitting FMP was able to get back into database and re-run the script with no problem.
