Is it all of your S3s that have the same problem? What do the status pages look like when they stop mining? Are the units on DHCP or static? What firmware are you on? If its a firmware after 1024, you will want to revert back to 1024 or the beta firmware below.
Can I get some beta testers for a new S3 firmware please? Download link is

Rolls back to the last good patch in Oct (1024), but fixes voltage adjustment and the important reset button. Hopefully.... let me know.

Ps in the future, please try and find support in the S3 thread rather than making a new one.
