Sysctl isn't related to that (it's used for setting kernel parameters); please don't touch it. You broke system by setting fs.file-max WAY too low, please execute sysctl -w fs.file-max=1628920 and remove fs.file-max entry from /etc/sysctl.conf. Like I said, /etc/security/limits.d/90-nproc.conf is example of config. You need to create file like /etc/security/limits.d/99-local.conf with contents like <user> soft nproc 8192 <user> hard nproc 8192 There is no need to reboot, but you need to relog into that user (and restart currently running processes under that user) - the limit is set upon login and will only affect new sessions. You should diagnose the situation to understand how you got 2118 processes running. This is unusual, typical desktop session uses less than 100. Some server applications that utilize thousands of threads (especially common for some java applications) sometimes need very high nproc limit, but this usually happens only for server workload. You should investigate how usual user got so many processes running, it might be a fork bomb or somethjing. -- Vladimir
