SRX5308 - Bug HTB: quantum of class

Hello,

I'm not in trouble anymore with my router but I wanted to show you how I solved a common issue in order maybe it would help community.

I used to have some logs with :

With somme deconnections of all WANs. Sometimes I have to restart manually the router.

Before that lines I had :

Thu Sep 22 11:25:13 2016((GMT+0100)) [SRX5308][System][NTP] Disabling NTP

I decided to change NTP settings, replace default NETGEAR NTP servers by french officiels NTP servers.
It solve my issue.

I don't know why NETGEAR NTP servers send some big trames.

If it's could help someone...

Have a good day !
