I have been suffering from repeatable crashes when scripts are run on my solution. It is being hosted on server 14.04 and I'm using OSX 10.11.3. The script runs fine in 13.
On investigation the cause looks like being a GTRR which goes to a layout with an on layout load script trigger as by changing the script to go to a layout associated with the same TO without the trigger and then changing layouts with the next script step fixed the crash.
Thank you for your post.
There is an issue with FileMaker Pro crashing when a layout is displayed with a sorted portal. Without seeing your file, is this possibly the issue?
Can you post the crash report up to and including the crashed Thread? This may give me a clue to a possible cause.
