If the VERSION file is empty then the startup may indeed fail.
My local 2.8 then fails with the error message
2016-07-04T15:30:46Z [8965] FATAL Database '_system' needs upgrade.
Please start the server with the --upgrade option
This is probably the same thing that you are seeing.
It should help to put the following content into the two empty VERSION
files:
{"version":20809,"tasks":[]}
and save them. Please note that "20809" means ArangoDB 2.8.9. If you're
running a different version, then the number should different (e.g.
ArangoDB 2.8.5 = 20805, ArangoDB 2.8.6 = 20806 etc.).
I hope this helps.
Best regards
