I am using sailfish X, on xperia X device.

Once in a while, I notice that my device gets hot, and its battery drains quickly. top shows that this is due do ofonod process, run by user radio.

Anybody knows what this process is, and how I can find out why this process is stuck in what seems like an active dead lock ?

I'm seeing the same behavior with my Xeperia X and it's very annoying. I'm using https://openrepos.net/content/velox/nofono to restart the ofono daemon when it's get stuck at 100% CPU. I haven't investigated further but it seems that it happens when I'm also using bluetooth.

Same here. I have to reboot my phone about once a week because of this. What makes it a real issue is that it drains the battery and may overheat the CPU, if the phone is left in an unventilated location...

I also observed this today after having connected my Xperia X Compact with SFOS to a car stereo using Bluetooth. @slava Do you know if this a known issue?

This is (still) a problem with Nurmonjoki

Happens (mostly) when there's BT, Android and gPodder running at the same time. So for me I have those running almost all the time.

the screen capture without user "radio" is the normal situation.

I'm having the same issue as well on my Xperia X Compact. Today I checked with top, seeing ofonod at 98-100% continuously. Today it most likely started after I sync my car with the phone (bluetooth). But it has happened already before (at least 1 time confirmed, other times I hv'nt investigated or the phone was dead due to battery depleted))

Didn't check on Sailfish but quick search revealed this: http://manpages.ubuntu.com/manpages/trusty/man8/ofonod.8.html https://en.wikipedia.org/wiki/OFono
