[Observium] Device randomly now taking longer to poll

Hi All

Im trying to work out why 1 of our switches has all of a sudden decided to now take 28s to poll, even tho using it for months its only taken 9s?

From the 'tab=perf' of the device, its showing ‘ports’,’fdb-table’,’netstats’,’ospf’ are showng as really high, 9sec each really?

I have restarted the equipment incase it was maybe that, same issue

Ive upgraded to the latest firmware too but still the same issue?

Any other ideas where I can look?
