FMSE starts with FMS itself so I'm assuming you are trying to launch it after it crashed. Is 701 the error in the log tracing back to the "crash"? Or do you get 701 when you try to re-launch it but there is another error in the logs to indicate that it stopped working?
What OS, what hardware?
thank you for your reply.
Indeed, I get the error in the log when I start the server itself, and then when I try to launch fmse independently.
The short version is: I get a 701 every time FMSE is launched.
Reinstalled FileMaker Server and upgraded the system (was 10.8.5). Same issue.
Current situation: FM Server 13v2, running on a Mac Mini, Mac OS X 10.9.3
