Description of problem: Yesterday, I tried attaching subscriptions in rhsm to a system, but I got the too many content sets error. Leaving firefox open, I gave up yesterday to deal with it today. I had the same issue a bunch of times and took a break from it. I looked back at the computer a few minutes later to see this error. So I wasn't doing anything too crazy when this happened. My vpn is still connected.

I'm facing poor wireless conectivity with Linux 4.7.6 (can't tell if it was like this before as I don't use this laptop very much). The stack trace looks similar to the other traces that were reported here so I'm including more information about my system.

Workaround in my case was to disable power saving (iwconfig $interface power saving off). It's been stable so far.
