Добрый день, Вадим,
I think you are overloading FileMaker and your computer. Are you running this on MacBook Air? This model (3,2) is quite low spec, it looks like you are running quite a few OnTimer scripts and it uses speak in FileMaker which I suspect behind scene runs built-in speak. You can try to trigger shell speak instead of FileMaker and send it to the background and may be iCal/system daemon to run FileMaker scripts instead of onTimer scripts.
My mistake, OSX shell command is "say" not speak.
Thank you for response!
MacBook Air - fourth computer I try to use in this task. Before I use MacBook pro (core 2 duo, and i5) with same result
On this computer works only one OnTimer script, and check one FM table.
Now I bypass this problem by prerecord audio files and call them from FM by afplay shell command.
Thanks for you solution, I also thought to do that.
This is a known issue in FileMaker Pro 13 and FileMaker Pro 14 on Mac OS X. Any additional information will be found on the Report a Product Issue Thread: Crash after "Speak" script command
