No free INGRESS ACL Virtual Slices on X670G2-72x

[bagro]

Hello,

recently we had a problem with re-configuring VRRP for certain VLAN on one switch working in MLAG configuration:

code:

...
 pibSendVirtualMacSourcePacketsToCPU(1:39, 00:00:5e:00:01:02, 1) - bcm_filter_install(0, 3762) returned "Table full".
...

code:

# show access-list usage acl-slice port 1

Virtual Slice : (*) Physical slice not allocated to any virtual slice.

We do not use either any user-based ACL nor vlan statistics monitor:

code:

#show configuration detail | include access-list
enable access-list refresh blackhole
configure access-list vlan-acl-precedence dedicated
configure access-list rule-compression port-counters dedicated
configure access-list action-resolution multiple
configure access-list zone DOS zone-priority 1
configure access-list zone SYSTEM zone-priority 2
configure access-list zone SECURITY zone-priority 3
configure access-list zone DOS application hal application-priority 1
configure access-list zone DOS application Dos application-priority 2
configure access-list zone SYSTEM application Cli application-priority 1

configure access-list zone SYSTEM application VlanManager application-priority 19
configure access-list zone SECURITY application Sentriant application-priority 1
configure access-list zone SECURITY application GenericXml application-priority 2

There are 4 Slices with no rules used:

code:

Virtual Slice 1 (physical slice 😎 Rules: Used: 0 Available: 256 user/other
Virtual Slice 3 (physical slice 5) Rules: Used: 0 Available: 256 system
Virtual Slice 6 (physical slice 11) Rules: Used: 0 Available: 256 IPv6 MC
Virtual Slice 8 (physical slice 6) Rules: Used: 0 Available: 256 system

Is it normal behavior? How could we release some unused Virtlua Slices ?
The X670G2-72x is running on 22.5.1.7
