Lost Connection on HP4108

Hi Guys

Newbie Here

I have flat network with 2324 pro-curve switches all linked back via fibre to a central switch ProCurve 4109gl (HP4865A)

Over the last couple of months, besides have a network loop (which i fixed) to central switch has been having alerts "Loss of Link" with a discription of Lost connection to multiple devices on port eg A2"

There is only a loss of connectivity for a few seconds and it comes back on line. This is happening on various ports radomly through through the day. The 4108gl switch is full with blades and modules. There are 5 servers connected directly and the rest are switches.

Has anyone come across this before, and was there a solution, before i fork out a fortune for a consultant to come in and investigate for me.

Thanks


Chris
