TCAM Issue in 93180 nexus switch

[Sagar4]

I have a nexus switch 93180YC-EX.

I'm getting below warning syslog message:

%TAHUSD-SLOT1-4-BUFFER_THRESHOLD_EXCEEDED: Module 1 Instance 0 Pool-group buffer 90 percent threshold is exceeded! (message repeated 1 time)

When I checked the resources usage, I found below output:

# sh hardware capacity

.

Please help in finding the cause and solution for this issue.

Hello @Sagar4 

Are there any recent changes in the network? (added ACLs, QoS policies, traffic increases)

Can you check if any interfaces show high output drops or buffer usage?

Are you using any QoS policies ?
