Specs: SonicOS, 499 MHz Mips64 Octeon Processor
We are using Sonicwall tz210 Since from long time. From fast 10dyas we are facing a problem with high CPU usage. Core 0 Process Monitor Shows tDataPlaneTask is using High CPU.

What is tDataPlaneTask? and why it is using high CPU?

✔ Best Answer
Remove all nic connections except monitor port and see if it drops. I suspect it is some issue with data on the switchgear. The task data plane is that process for that part I think. As to why it is high is unknown. Might be an issue with some port like a jabber or maybe the port panel is going out??

To be sure email dell and see if they'd offer more clues.
