Hi Jay,

This limit also depends on how long the kernel needs to revalidate your flows. 
For more details take a look at the following blog post:

https://developers.redhat.com/articles/2022/10/19/open-vswitch-revalidator-process-explained

For testing you can use the “ovs-appctl upcall/set-flow-limit <limit>” command, 
which will directly configure the flow_limit. But this is for testing only, you 
should not use it in production.

Hope this helps.

Cheers,

Eelco
