GS510TLP intermittent connection loss

Have multiple VLANs setup which supply (supposed to anyways) internet to multiple tenants.  Most of the time it is working but having multiple drops through the day.  Very short few second or so drops.  Troubleshooting with the router technical support shows that when the drops happen the packet doesn't reach the edge router.  Only thing really in between the client router and edge router is the GS510TLP.  Wanting to run some troubleshooting tests, look at logs etc.  Not super familiar with this model and it's features as far as those things go.  Thanks!
