The sole purpose of those lines you mentioned is thus to identify timeouts.

Of course once you do that you can also fix jive_jiffies() to perform the roll-over itself at some `safe` time. Another option for testing in this case would be to upgrade LUA to 5.4+ and replace all instances of `lua_Number` (signed) to `lua_Integer` (unsigned), which should either shift the restart to after 49 days or possibly continue indefinitely. ------------------------------------------------------------------------ gordonb3's Profile: http://forums.slimdevices.com/member.php?userid=71050 View this thread: http://forums.slimdevices.com/showthread.php?t=111650 _______________________________________________ Radio mailing list Radio@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/radio
