I ran top recently and filtered by memory usage
Code: top - 10:48:04 up 150 days, 4:31, 1 user, load average: 0.00, 0.01, 0.05
Tasks: 79 total, 1 running, 78 sleeping, 0 stopped, 0 zombie
Cpu(s): 0.0%us, 0.0%sy, 0.0%ni,100.0%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st
Mem: 435132k total, 334640k used, 100492k free, 39608k buffers
Swap: 262140k total, 6120k used, 256020k free, 195700k cached
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND

Why is python using so much memory? Is that normal? I don't recall seeing python near the top of the list when I've monitored memory usage before.
Should I investigate any long running python scrips that might be running?
Thanks!

| It depends on what it is doing, I suppose. That's about where I'd expect it to be for a modest Django project. |

Your Python script is only using 7.6MB. It's the RES column that matters.
Also, your total memory usage is just around 100MB (334640k - 39608k - 195700k), so you have a lot of room left. |

Should I be concerned with the running time?

| It depends what the process actually is, lots of things use python, what does Code: ps u -p 2355 output? |

aha, it's the denyhosts script. ok, looks like nothing to worry about then, definitely want that one running.
Code: #ps u -p 2355
USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND
root 2355 0.0 1.7 58556 7608 ? S 2011 4:27 python /usr/sbin/denyhosts --daemon --purge --config=/etc/den
Thanks for your help!
