Hello guys

If I reboot the MT, all dtraffic data in simple queues are lost.
It’s a bug in 2,9 RC5 or it 's normal??
I want kept the data of simple QUEUES.
Is there a possible??

Are you referring to data like traffic volumes / packet counts etc?
Then yes expect to lose that on a reboot.

What ROS version are you using and on what device?
