All simple,
IOL images are not ideal, I recommend raise memory for IOL SW or try another switch image

Do you mean vIOS or IOL L2 / L3 Images?

I have exact same issue.

All devices are L2 IOL
Six switches running fine, one switch - lets call it S1 - has a linux box connected.

All configurations, connectivity and routing (OSPF, LDP, MP-BGP), operating perfectly.
I can ping from S1 to the linux box and vice versa without issue.

If I ping from any other switch in the network to the SVI for the Linux box on switch S1, its fine.
If i ping through S1 to the linux box, the switch S1 is crashed / moves to status off in eve-ng

I tried increasing memory, same issue.

Are there any further diagnostic logs to identify where the error is here?
