Hi everyone,
I have a FreeBSD 7.0-Release server that started to swap after an error
in a shell script (process spawning competition ;-) ). I killed the
shell and the RAM is now OK. The problem is that the swap is still used.
How can I "reset" the swap?
You don't. The system will handle it for you, I promise. :-)
And very well, too.
You can prompt it to move pages back into RAM if you start using a swapped-
out process again - say, for example, a quiescent word processor had been
swapped out, you could get it back by raising it and starting to type.
But as Kirk said, there really is no need. It's one of the kernel's many
jobs, and I'm inclined to leave it get on with it!

Thanks for your answer. I'm asking here because it's been several days
and there is still used swap for data that should never be used anymore.
If the kernel wants to keep it, why not move it to RAM now that there is
some free?
Why bother if it isn't being currently used?

Because this server is monitored by Nagios and it emails me every hour a
warning because the swap is not 100% free (I know it's pretty extreme,
but I want to know if the system is swapping).
I just tried
swapoff -a ; swapon -a
and it worked great.
Thanks everyone for your answer.
Martin
