Thanks for the kind words. I also had severe stability problems but they were resolved by disabling the automatic indexing (built-in function in the Syno) and by switching to sqlite3. Now it is running very stable.

What I did to get around the dreaded HUP problem was to rename /usr/syno/bin/synoindex to synoindex.old
It’s a heavy handed approach but it stopped the damned indexing and the HUP problems haven’t been seen since.
