I was trying to look at the whole list of installed application from Warehouse -> My Profile -> View full list (on a Jolla w/ SFOS 2.0.0.10). The app was busy and didn't finish its task and show the list.
A few minutes later (when I was able to plug the phone to the desktop in order to have a better terminal) I ran a strace on the harbour-warehouse that was using 130% of CPU and 30% of RAM.
The output was a long repetition of the following excerpt:

The access() is retried every 3-4 s.
Any idea what's going on? No need to say that those .db-journal and .db-wal files indeed do no exist. Only the .db file is there.
