I'll be looking into why we're getting critical swap alerts, and I'll find something like:
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ SWAP COMMAND 14683 user1 30 10 16.0g 772m 744 S 0.3 0.3 277:24.87 6.5g MATLAB 14576 user1 30 10 8125m 1.1g 736 S 0.3 0.4 261:16.73 4.1g MATLAB
where the TIME+ column is frozen for those processes.
My question is, in the above, what does this imply?
As I understand it, stopped time means that it's a dormant process/not being processed by the CPU. However the above example shows 0.3% CPU use, so despite the fact that it's very small, shouldn't the time column continue incrementing?
Are these processes "finished"? In which case, how are they cleaned up? Does the user who started them need to acknowledge them or something for those resources to be freed up?
