broadcast storm in PPPoE ISP network, help

hello from india, a big time ubnt user.
i have 2200 customers now and all are on pppoe only.
My network design : Core Microtik Router CCR1036 >> UBNT EdgeSwitch >> Unmanaged and Managed switches mixed >> Customers on PPPoE.


Since last few days, my customers are complaining that, they get a lot of packet loss and disconnection randomly in every 5-10 minutes. In all the managed switches I have RSTP off and Loop protection on and Broadcast Storm for broadcast, multicast, unicast on for 1M in each switch.

And whole day, each of those managed switches log keeps on showing, BROADCAST STORM APPEARS ON PORT X , MULTICAST STORM APPEARS ON PORT X.

I guess, since the whole network is facing heavy broadcast storm, may be thats the reason, Im losing packets and facing random ping cuts to our devices and wireless access points and all managed switches or whatever and thats the reason, the customers are dying.


Is there a way to completely stop or kill the whole broadcast storm ?

What is the reason, why its happening ?
