Since SFOS 1.1.9 Sailfish shuts down unused applications automatically. In some cases it is a quite annoying think eg. it shuts down media player when I write email (and listen to the music) or so. Is it possible to give some applications higher priority making jolla shutting them down less often? Cheers, Mariusz

As SailfishOS is based on Linux you can do the following (you need developer mode installed and root [devel-su] access for this):
Users and system administrators have often asked for ways to control the behavior of the OOM killer. To facilitate control, the /proc/<pid>/oom_adj knob was introduced to save important processes in the system from being killed, and define an order of processes to be killed. The possible values of oom_adj range from -17 to +15. The higher the score, more likely the associated process is to be killed by OOM-killer. If oom_adj is set to -17, the process is not considered for OOM-killing.

PS: PID is the Process ID you can get with ps aux | grep processname or from top
Yes exactly though it might be in a group of processes that have a certain priority set (cgroups)

Maybe, at least, if application is closed by OOM killer, it should restart with the last configuration? Looking again for the album I have been listening to before the email arrived is additionally annoying...
I think this needs app changes or a big multitasking change which could do a suspend to disk for a process. Though that might eat up a lot of internal space.
