Hello,

Can you try and Isolate each of the switches, this may helpyou pinpoint the
source of the problem. Its basic but its helped me many times. You will need
to disconnect live network users.
Also you can try and see if there is a trend, does it happen during peak
usage hours or is it happening throughout the day, including low usage
times.

Regards

Raymond
