limits on number of ports/sessions to switches from ostinato

[Peter Zhang]

we are trying to scale out with Ostinato connecting to 127 switches ( 3 ports per switch ), we are hitting an error "too many open files".

Is there a limit on how many sessions/ports we can establish between Ostinato and switches ?

Thank you

Peter

Peter,

I'm not sure, I understand your topology/connectivity.

Where are you running the Drone agent? How many Drones are you
running? How many ports does the device running drone have?

A diagram would help to understand.

It's just one drone connected to a mininet network on the same VM server

Thanks

You might be hitting the Linux kernel limit. The current max limit can
be viewed and changed using the "ulimit" command -
https://ss64.com/bash/ulimit.html

You will need to restart the process after changing the limit.

Let me know if that fixes the issue.

Peter,

Did 'ulimit' solve your problem?
