This message indicates that the call to the operating system to determine how much disk space is available has returned an error. This implies that the operating system does not enable applications to determine how much disk space is available.
Resolution:
It is the system administrator's responsibility to ensure that sufficient disk space is available, as the Fileshare Server is unable to determine the amount of free space available on the drive. If the Fileshare Server is unable to write a recovery log file because there is insufficient disk space, the Fileshare Server automatically closes down.
