Index upgrade fails on Windows Host

[gebolze]

We've recently tried to update prometheus from version 2.1 to 2.2 on a windows host. We expected that the service will upgrade the index and then start serving http request. But instead we've got the following error messages in the logs.

.\prom_2.2.0\prometheus.exe --config.file=.\conf\prometheus.yml --storage.tsdb.path=.\data --web.listen-address=0.0.0.0:9999

We've tried the same update on a comparable linux host and the index upgrade completed without any problems.
