[SOLVED] Dbus and child processes freeze randomly

pie86 · 2016-09-10 08:34:21

Dear All,

I've been experiencing some problems with my openbox environment lately. After a while (10-60 min) the set of processes launched at xinit time by openbox enter status "T" which means "stopped, either by a job control signal or because it is being traced." (quotation from SO Topic) and, afterwards, most of the applications freeze. Nonetheless, I can always open new applications switching to another desktop of my openbox session.

Here's an htop screenshot taken immediately after the freeze:

I was not able to find any relevant information in the docs nor backtraces of dbus-launch in coredumpctl.
Can someone please help me identifying the problem?

Thanks,
Pietro

P.S.: memtest86+ reports that memory is fine.

Edit: removed large image and added thumbnails. Sorry about that.

Since when I removed dbus-launch from my .xinitrc I haven't experienced new freezes.

My .xinitrc now reads:

exec openbox-session

Fingers crossed...

No need to cross your fingers; the move to dbus from libdbus deprecated dbus-launch.

Damn, I missed that in the news! Thank you!

I also missed the change that is needed when launching the window manager.

I was launching my xmonad with "exec dbus-launch --exit-with-session xmonad". I replaced it with "exec xmonad" and the issue is gone.

Here is another thread where we didn't figure out it was related to dbus.

Thanks.
