I had read the FAQ previously, though it had been a while, so
thank you for reminding me to read it again.
I assume the relevant part of the FAQ is question is question on
why X takes so much memory (I'll admit to only skimming the rest
of the FAQ). The main points of this section seem to be that yes
X can take up a lot of memory, often for other processes, but
that it is OK because even if it is not deallocated, the memory
will eventually become inactive and be swapped out.
Well, my problem is that this memory is not being swapped out. Or
rather some of it is swapped out, but then swap fills up. As
I said in the portion of of my message that was snipped above, I
get to a sitaution where processes can no longer allocate memory
because X has control of too much. At that point processes start
dying spontaneously, starting whith big memory users like
mozilla, but eventually even smaller processes apt-get and some
wm* apps start dying. At this point I am forced to reboot. So
this is not just another case of looking at top and thinking that
X is too big. X, or some process that it is allocating memory
for, is holding too much memory and it won't let it go.
Which leads new that the FAQ did teach me,
cat /proc/$(pidof X)/maps . Unfortunately I haven't been able to
decipher it.
I waited a while to reply because I wanted to try adding some more
swap, to see if that would help. It has increased the time
until I start to get problems to 5 days, but the problems still
occur. Mozilla just died on me because it couldn't get memory, and
other processes will start doing the same soon if the behavior
holds.
Below I have attached my XF86Config-4 and the results of
cat /proc/$(pidof X)/maps .
Thanks for your help.
