Comment 11 for bug 1480877

hitting the same issue once and a while.
it happened again yesterday. i could record some traffic on dbus:

this pastebin shows the log with high performance impact.
at the end of the log things are getting normal again:

this pastebin in comparison shows the traffic after things settled and the phone was usable again.

both recordings are about 1 minute.

maybe this helps to track it down...
