Hello Sylvain ! If my assumption is correct (KDE open a huge number of files during the query),
So you had to increase the number of files open with > sysctl kern.maxfiles=102400 you can put it on `/etc/sysctl.conf` like this at every boot kern.maxfiles will be setup to 102400 also, you had to change your /etc/login.conf put these two lines to staff group ``` :openfiles-max=102400:\ :openfiles-cur=102400:\ ``` A little reboot is necessary, and everything will work ! ;)
