- ReadFile and WriteFile functions in Windows have BUG:
- If you Read or Write 64MB or more (probably min_failure_size = 64MB - 32KB + 1)
- from/to Network file, it returns ERROR_NO_SYSTEM_RESOURCES
- (Insufficient system resources exist to complete the requested service).
- Probably in some version of Windows there are problems with other sizes:
- for 32 MB (maybe also for 16 MB).
- And message can be "Network connection was lost"
