Interface Errors after upgrade - VM Series

L1 Bithead

Hello,

 

we upgraded our Palo Alto VM to 11.1.6-h1, after the upgrade the monitoring system gave us warning about the errors increasing on the Firewall interfaces but the clients did not report any issues, so it's not affecting them at all,

 

this is what i see on one of them:

 admin@paloaltoVM(active)> show interface ethernet1/5

where should i start to troubleshoot this ?

 

I didn't found any known issue in PANOS 11.1.0 related to this behavior,
