Sideband send data limitation

I'm experiencing a TMM core dump on the Sideband send command when I'm trying to send data of 32MB+ Is there a limitation on the amount of data that can be send through the sideband ? Thanx

Hi Cassie,

 

There's no hardcoded limits to the amount of data that can be transmitted over a sideband connection. This might be through the way you're irule is configured along with a specific bug on the version you are running on.

 

Is it possible for you to post anonymized copy of the irule? The community could probably help with the code. Otherwise I would look towards F5 support to see if you are running into a bug with your iRule.
