Hi

I'm running a FreeBSD 4.11 system on my laptop, before that i had 4.10
and it's always worked great, i can't think of any new major changes
i've made or things i've done in the last months. Just recently it
started unmounting my swap partition for some reason, i get no warning
but i have started checking dmesg and see it happen. Only a reboot can
fix it, i've tried doing swapon /dev/partition as listed in fstab but it
returns invalid argument. One warning signal which i can see if i
continue using the laptop like usual for a while after the unmount is
that firefox gets killed, or any other heavy application. Of course this
is a cause of not having any swap mounted and dmesg tells me that.

As i had recently switched to XFCE from fluxbox i suspected it was too
heavy for my laptop but switching back to fluxbox made no difference.
One thing that did happen just before the problems was a lib issue after
a portupgrade, it forced me to map a few libs to their current versions
in libmap.conf but i had it running for at least a few weeks after that
without problems, it is hard to tell though.

This is my libmpa.conf file.
=========
#firefox

=========

This is the message i get indicating that my swap partition is no longer
mounted.

swap_pager_getswapspace: failed

I sure hope someone knows what to do and if you want to suggest
migrating to the 5 branch then thats ok because i've been thinking of
doing that.
