I'm chasing down some performance problems on a Linux server, and I've setup BSD process accounting to track down what might be causing the load. However, I'm seeing a lot of processes called "Filesystem", like this:
sed root ?? 0.00 secs Thu Oct 22 06:00 Filesystem F root ?? 0.00 secs Thu Oct 22 06:00 sed root ?? 0.00 secs Thu Oct 22 06:00 Filesystem F root ?? 0.00 secs Thu Oct 22 06:00 Filesystem F root ?? 0.00 secs Thu Oct 22 06:00 which root ?? 0.00 secs Thu Oct 22 06:00 which root ?? 0.00 secs Thu Oct 22 06:00 cut root ?? 0.00 secs Thu Oct 22 06:00 grep root ?? 0.00 secs Thu Oct 22 06:00 Filesystem F root ?? 0.00 secs Thu Oct 22 06:00 cut root ?? 0.00 secs Thu Oct 22 06:00 Filesystem root ?? 0.01 secs Thu Oct 22 06:00 Filesystem F root ?? 0.00 secs Thu Oct 22 06:00 grep root ?? 0.00 secs Thu Oct 22 06:00 Filesystem root ?? 0.00 secs Thu Oct 22 06:00
I don't have a program called "Filesystem" on this machine, and Google isn't telling me anything useful about what it might represent. Has anyone dug into the source code or otherwise knows why these would be popping up?
