What tools do you use to track down mem. management issues?
Any specific kernel tweaks?
Try iotop....
OK, so the gentoo wikis says the only kernel modes for iotop are
General setup
-> CPU/Task time and stats accounting
[*] Enable extended accounting over taskstats
[*] Enable per-task storage I/O accounting
Do you add any others? Do you build a specific kernel for these sorts of
low level account and debug codes to work, as reading about, some
can cause noticable performance degredations. So do you have a special
kernel to track these problem and then return to a production kernel,
or leave them in all the time?
