[Devil-Linux-discuss] RAM Usage

[Matthew H. <mat...@va...>]

Hi Guys,


We have around 150 DL boxes out in the wild now, and there may be a
small problem that keeps happening. Under heavy load the boxes will
start running low on RAM, at which point we get malloc errors for some
daemons running on the unit. First thing to go is usual snmpd, which
isn't a major issue. But further down the line we start loosing things
like ssh, and in some cases even more crtical processes.=20

Ok I know this is pretty much the problem with running things from RAM
disks, but is there a way to ensure that network/tcp connections cannot
steal all the RAM etc and effectively reserve RAM for the OS?

BTW we aren't being tight with the RAM, most of these boxes have 512Mb
or a 1GB, which should be able for effectively routing traffic and some
traffic aggregation.

I welcome any ideas on this front.

Cheers

Mat
