Huge mem leak coming from somewhere, can't kill process

Hi all, move this to ports forum if it is indeed to do with them, but i'm not sure.

I haven't worked out which application it is, but after running something the whole system slows to a halt and I see from top;

Code: 
blackbox# top
last pid:  2777;  load averages:  0.12,  0.17,  0.12                                                                  up 0+02:59:44  12:35:07
94 processes:  1 running, 93 sleeping
CPU:  3.0% user,  0.0% nice,  0.0% system,  1.1% interrupt, 95.9% idle

It seems these processes are to blame, but when I try to kill them *nothing* happens, as in, I can try and kill them within top or with the kill command, but they just do not listen, even when killing them as root.

What is up with these super-human processes? Where are they from and why can't they be killed!?

Thanks, Ben
 
Use ps command to grab top 10 memory eating process:

Code: 
ps auxf | sort -nr -k 4 | head -10

You may have to adjust syntax a little bit for bsd system.

Thanks, but I can already see the memory chewing processes, I want to know where they came from (i.e. what's called ld) and how to kill these indestructible beings.

Are you running linux programs?

Yes.

I had a suspicion this could be the problem. The only ones I can think of are linux-flashplugin and acroread (and google earth if it's not native - I can't remember)

Any ideas what could be causing it? It certainly doesn't happen *all* the time.
 
Install sysutils/pstree. Then post a pstree -w when this problem occurs, so you can instantly see, which process is responsible.
A dynamic linker allocating 2G mem, seems very suspicious.
