It appears the change I made wasn't what was needed. I took a nap, after doing today what I used to do on Friday, which involves going to Doctor, getting shots, then shopping around town etc etc. Anyway, I woke up to Qbittorrent being gone. It crashed at some point. In the notification thingy, it had a few of the file open errors again. So, I ran some of the commands you posted, my hard limit was set to 4096. I whipped out my calculator and doubled it. I set it in the limits.conf file like so: root@fireball / # cat /etc/security/limits.conf | grep nofile # - nofile - max number of open file descriptors * hard nofile 8192 root@fireball / # I logged out and back in. I ran the command you shared and it was indeed set to the new amount. I'm going to upgrade qbittorrent to the new version again and test it some more. Thanks much for the help. Maybe this will fix it. Dale :-) :-)
