[c-nsp] RSPAN VLAN filter & TCAM issue

[Alex Wa]

Hi guys,
 
We're receiving this log message when trying to apply a vlan filter to a RSPAN VLAN. 
 
Apr 10 13:36:08.580: %FM-4-TCAM_ENTRY: Hardware TCAM entry capacity exceeded
Apr 10 13:36:08.580: %FM-2-VACL_FAILURE: Interface Vlan100 traffic will not comply with VACLs in ingress direction(s)
 
We don't have any access list applied to any interface except the VLAN filter , and in total 16 access-lists. the sh tcam counts is below (when the output was taken the vlan filter wasn't applied)

Cisco's error decoder recomends to delete unused access list but we can't reduce no more and 16 acess lists  is a normal, if not low, amount . 
 
any hint ?
 
thanks in advance,
