"Insufficient free memory" on C2950G-48 : any tuning possible ?

[p.devalck]

Hello,

on a catalyst C2950G-48, there seems to be a memory problem (insufficient free memory).

The number of VLANs handled in transit is quite big (could be as much as 100), but MST is used rather than Standard STP.

In which way can I check which switch process is the cause of the problem ?

Is tuning possible ?
