What does it takes to bring a system down to its knee ?
Hi there,
I wrote a little program that parse recursively all file found
within a toplevel directory. As soon as the process start my whole X
session (KDE/debian stable) becomes completely unresponsive. I manage
-painfully- to start a top to monitor my process:
It is returning:
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
21007 mmalater 18 0 118m 62m 1120 D 3 1.6 1:14.08 gdcmscanner
...
AFAIK that does not seems to neither: memory hungry nor process
hungry. Is this correct ? If so this means my system is getting slower
because of the disk operation, right ? Any tool to monitor that or
track down why my system is so unresponsive ?
This is a 4 processors machine with 4Gb or RAM (Linux zorglub
2.6.18-6-amd64 #1 SMP Mon Jun 16 22:30:01 UTC 2008 x86_64 GNU/Linux).
Filesystem is LVM over ext3fs (I think, can't remember).
thanks
