[Bug 1491566] Re: Shell not responsive after an incoming SMS or call notification

 

i succeeded in getting my device stuck in a frozen state. it seems alive, i can interact with the shell, top shows processes running and updating.
trouble is, gdb t a a bt yeilds no output. bt and bt-full result in "No stack."

I did check the unity8.log and noticed the log is fairly normal, until
the end where is spews "cannot open file <name> too many open files" so
i grabbed a dump from lsof as well.
