Hi, I have installed Redis 4.0.14 on Windows Server 2008 when I try to save a json (about 7 MB) in Redis Cache, I have the attached exception "EXCEPTION_INT_DIVIDE_BY_ZERO" and the windows service stop to run. I don't have this problem on Windows 10 with the same data. I have the maximum default size of Redis Memory set to 100MB in the operating systems.

Could you help me , please? Thank you.

@ap86fn unfortunately I have no access to Windows Server 2008, so I just tested this on Win10, but as you wrote - it works fine. Issue seems however to be related to obtaining the value for:
PORT_LONGLONG stat_fork_time; /* Time needed to perform latest fork() */
In your case it gets set to 0, hence the exception "EXCEPTION_INT_DIVIDE_BY_ZERO" as that value is used in calculation of value for stat_fork_rate; /* Fork rate in GB/sec. */. I doubt it could be so fast to yield almost no time, so it might be either related to accuracy/value rounding or some difference in Windows API.

@ap86fn if you desperately need it running on WS 2008 R2 - please re-open this ticket and I'll try to test it in such environment

workaround for issue #46
5a40a37 
- in Windows prior to 8 and Server 2012 there is no GetSystemTimePreciseAsFileTime(), so in case of
  very fast forking - we take 100ms for calculation of "stat_fork_rate"
- fixes #46

HI @ap86fn,

After some investigation it turned out that a WinAPI function GetSystemTimePreciseAsFileTime is available only from Windows 8/Server 2012, so in case RDB/AOF were created fast enough - duration measured with default GetSystemTimeAsFileTime (used when the former is not available) yields 0, which caused this exception. Now, as a workaround (as I don't think it is that important to have that statistical value perfectly correct) - a 100ms duration is assumed, which does not make any problems anymore. I will release a hotfix for 4.0.14 this week then.
