Ah, I forgot, this is a 3.0.x series kernel - we can throttle that cpu hog if we want to:
Code:
[root@kindle root]# cat /proc/20321/limits
Limit Soft Limit Hard Limit Units
Max cpu time unlimited unlimited seconds
Max file size unlimited unlimited bytes
Max data size unlimited unlimited bytes
Max stack size 8388608 unlimited bytes
Max core file size 0 unlimited bytes
Max resident set unlimited unlimited bytes
Max processes 4016 4016 processes
Max open files 1024 4096 files
Max locked memory 65536 65536 bytes
Max address space unlimited unlimited bytes
Max file locks unlimited unlimited locks
Max pending signals 4016 4016 signals
Max msgqueue size 819200 819200 bytes
Max nice priority 0 0
Max realtime priority 0 0
Max realtime timeout unlimited unlimited us
Hmm...
It (cvm parent thread) is only showing me a screensaver, and:
Code:
[root@kindle root]# ls -l /proc/20321/fdinfo | wc -l
741
and it has 741 file descriptors open (almost its soft limited number).
Edit:
If the author of cvm forgot to close any unused file descriptors of the 3 standard file descriptors per thread -
HTOP showed 243 threads, *3 == 729 file descriptors.
I think I see a relationship there.
And if the author of cvm decided to poll that many file descriptors . . . .
Well, see:
https://daniel.haxx.se/docs/poll-vs-select.html
and the reference it links to.
