Re: Cron Running As UID 400
Wayne,
The only reason why a Cygwin process runs with uid 400
is that its SID was not found in /etc/passwd when first
starting from Windows (you can observe that by temporarily
renaming /etc/passwd and starting a fresh Cygwin process).
It's stange that this happens only for one cygrunsrv process
Please use the Windows Task Manager ("Processes" tab) and
report the User of the strange cygrunsrv, according to Windows.
