Broadcast storm like symptoms on network

Hi guys,

I'm getting a weird issue with our network. We look to be getting broadcast storm symptoms but not actually getting the results of a broadcast storm. All the switches are blinking in sync with one another, but we get no network slow downs or outages.

​

I've had wireshark running for about 10 minutes to pull some info. Is there anything I should be looking out for? or stuff I can trim from the wireshark display to help narrow down.

​

I am no network wiz so please go easy on me.
