Hi wook_sf, I followed another thread to set the smartsearch priority to 10. I don't think smartsearch is the culprit because it doesn't show up at the top of htop and I haven't installed any new apps or made any changes to my filesystem where it would need reindexing. As a last resort, I will try to disable the execute bit as you suggested, but does that mean any new contacts/apps I add will not be searchable? If that's the case, then I can't do that because I rely on search. Cheers, Tom
