The values are in KB... the box would have 6GB, and a 2GB
swapper.
Yep. You ran out of RAM and swap-sapce ... 68Kbytes
available for swapping.
The question would be what services you're running, and
who gobbles up all the RAM. Have a look at the output of
top, sort by memory usage. With top running, press Shft-m
Cheers,
Tink
P.S.: Next time you post system output please enclose it
in code-tags, that makes it more readable :}

hi tinkster
its all apache, mysqld, postgres, mailman and a few more others running multiple instances... i have like 15 mysqld processes running.
even still, adding this all up won't hog all the 5 GB of ram.
any other ways?

Please run this

and post the output inside a quote
[ quote] [ /quote] (without the space
after the opening square brackets.

OK, so according to
Code:
awk '{if(sub("M","",$6)){$6=$6*1024}; total+=$6 } END{print total}' processes.txt
your processes use up 701540K ...
That strongly suggests that some process is leaking
memory. What distro are you running, and where
did the programs installed come from?
Are you able to reboot the box and take a snapshot
of top like the one before? And of course the output
of free.
To actually assess which processes are chomping up
the RAM you'd have to run each of them under valgrind,
from memory (older posts I read somewhere) I recall
that Apache & MySQL as a combo had that problem
at some stage, can't recall when, and how it was fixed.
Cheers,
Tink
