VSP8404C System Uptime Resets After Every 497 Days ?

Hi Sirs
We have encountered VSP 8404C after 497 days, the system automatically rebooted
We also searched related KB and found that the following models describe why this problem occurs
Ethernet Routing Switch 4500 running any supported software version
Ethernet Routing Switch 4800 running any supported software version
Ethernet Routing Switch 4900/5900 running any supported software version
Ethernet Routing Switch 3500/3600 running any supported software version
Any supported software releases
ERS devices rely on RFC1213's sysUpTime which is a 32 bit counter in 1/100 second and wraps around every 497 days.
So I also want to understand if VSP 8404C also has this situation
