It is not an SSD but newest WD with 250 MB/s speed. The problem is application constantly grows in size because of memory leak and eats all the memory and swap, and while other applications are relatively small unloading them to swap is useless. And after app is killed and I can't get unloaded apps to work - they are unresponsive: whether kernel or KDE fails to tell kernel to unload them so forced to reboot machine. Which was not the case in 2.x versions of kernel where I was able to set swat 2-3 times bigger than memory, while now 1:1 proportion is useless. So trying to understand what is wrong here: kernel settings, KDE or whatever? -- You are receiving this mail because: You are on the CC list for the bug.

No at all! As I can't get system to work after swap: kernel does not unload applications from swap - forced to reboot. Also start swapping does not makes much sense moreover with 20% as it will take hours until single application will fill 16 GB of the swap and kernel will load/unload it all the time. If single app - takes all the memory it should be killed. And what happened with linux?! Why swap starts to work so badly like I said in Comment 23? > "-p" we can add.

Should work (for SIGTERM) if both conditions are met: both RAM and SWAP bellow critical level. If only one type of memory is nearly fully used, EarlyOom will do nothing. -- You are receiving this mail because: You are on the CC list for the bug.

Send SIGKILL if at or below KILL_PERCENT (default PERCENT/2), otherwise SIGTERM. You can use -s 100 to have earlyoom effectively ignore swap usage: Processes are killed once available memory drops below the configured minimum, no matter much swap is free. -p Increase earlyoom’s priority: set niceness of earlyoom to -20 and oom_score_adj to -1000 -- You are receiving this mail because: You are on the CC list for the bug.
