Cannot ping/telnet to 4104gl and 4108gl

Frequently you cannot ping the switches for 5-15 sec.
Equipment connected to the switches you can ping.
Its a flat network, no routing and 3 x 4100 and 4 x 2650 switches.
4100 sw version G.07.93.
2650 sw version H.08.72.

(Before the 4100 was upgraded from V.7.79 the hole network was down 5-15sec. and the MAC fx. of a PC had gone from the MAC table in the switch.)
I am not onsite the lokation, but still suspect the MAC table.
Has anyone seen some like it?

i'd suspect you've got a CPU load problem. but some background first.

you mentoned this is a flat network. are you running Spanning Tree? is this a Star Pattern network? which is the core switch? what's your uplink speed?

There have been Innumerable people who have helped me. Of course, I've managed to piss most of them off.
