Write error: ssl=000000001C1758B8: I/O error during system call, No error

### Environment:

Windows 7 64-bit (with 64-bit oracle jre 8u161)
Conscrypt 1.1.3

Unfortunately I don't have a repro. The system normally works, seeing these occur every day or two after extended use, only from windows as far as I'm aware.

```
