High RAM usage

[Monviech (Cedrik)]

Sorry to say but didn't you check the attached file the OP posted? You can see the broken child processes spawned in it. It's a php script that doesn't terminate.

theres like 200 instances that use 60mb each which fills the RAM and SWAP completely.

It has nothing to do with ZFS.

[cookiemonster]

It doesn't appear for me. I am using a work machine working from home where all sorts of security stuff is applied that can prevent showing attachments and other potential sources of trouble.
That said that, the case might be of broken system but the principle is correct.

I'll post some of the content to make it clearer:

[cookiemonster]

Ok thanks. That is something defo wrong that will just use up resources.

[CJ]

I'll also point out that zfs doesn't tend to chew up your swap. :)

[cookiemonster]

Of course it doesn't but if you have processes using up memory, it is well known that ARC might not be freed fast enough before contents overspill to swap.
I've seen the attachment now and I although the zfs usage post I made is technically correct, i was off the mark with this one. These are definitively runaway processes.
