We have a FMP 11 Server running on an OS X server. We had SEP (Symantec) installed but discovered that it was causing FMS to stop serving databases using IWP (instant web publishing). Restarting the server would fix it but it would stop working again within a few days or weeks. I removed SEP and it hasn't failed since.
We had an exception configured to ignore the live database directory.
Has anyone else had this problem? What else might we need to do to prevent this from happening?
