FS core down soon after Forward Clock Skew Detected in windows
FS core down soon after Forward Clock Skew Detected in windows [CRIT] switch_time.c:974 Forward Clock Skew Detected! os is windows server 2008 R2 64 bit, in VM ware what can i do to reduce the occurence of clock skew? increase CPU capability or run FS in a real machine? anything i can do with FS conf xmls?
Try another type of virtual machine. Xen seems to work well, openvz is recommended by the devs. Other than that make sure your resources are allocated properly.

If you're going to run FreeSWITCH inside a virtualized Windows Instance, you may as well go with Microsoft's Hyper-V. Windows Server seems to work better under Hyper-V than Xen or OpenVZ. You could try assigning the VM a higher CPU weight, (not sure how VMware handles that) to see if that solves the issue.

There is also a vmware setting that controls if you use real timing or emulated and the emulated won't cut it. I always say FreeSWITCH is Free, use the money you saved to give it a good home. On Tue, Jul 23, 2013 at 1:47 AM, Jeff Leung <jleung@v10networks.ca> wrote:

It might help if you start FS with "-monotonic-clock". This usually makes the timing more accurate. However, on a VM you can never be sure. Also, if I understand your first post correctly, when this error is shown, it will bring down FS completely? If that's the case that must be reported to Jira, since this is a bug (a crash is always a bug). To make sure that timing is ok, always run on real hardware. /Peter 2013/7/23 Jeff Leung <jleung@v10networks.ca>
