what is the PC Config process in the show cpu output?

[rkhanso]

There are a few posts in the forum with people asking about the PC Config process/task in the sh proc cpu output, but no one has ever answered what that process is.

I've seen it jump up to 90% for short periods of time.

Would someone explain what this PC Config process/task is?

Thanks.

Were you viewing the CPU in the web interface? Sometimes the web interface has a tendency to make the CPU spike for a short period.

Let us know if you have any questions..

Thanks,
