The only module I know about that is 'tainted' is the philips webcam
compression module pwcx, which I forced loaded with 'insmod -f'. But
unloading that didn't change the problem. Anyway the 'tainted' issue
has to
do with no being in order with the GNU licence isn't it?

When I do lsmod (after reloading the pwcx module) I get:

Memory modules can age and can create the funniest problems when under
different load. I have a machine that handles RSYNC copies of several
GBs perfectly and every application that tries to shove the very same
GBs over NFS to the fileserver crashes with similar error messages as
you have provided. Maybe ices also stresses some memory pages more or
different to other applications. Try running memtest86 on your machine
if you can take it offline for a couple of hours (or days). You can also
test your modules in a different machine if you need the machine in
question.

It might not. Which GCC and which kernel did you use?

No the best thing to do, is not load the module to start with, unloading
the module may mean nothing as it's already had access to the kernel.  
You more or less on the right idea with what tainted is, although it's
really a check for modules that don't have the typical open licenses
like GPL and BSD. Only a reboot will be sufficient for clearing the
tainted state.

it's better to check, A good memory test is the memcheck program but
also doing heavy compiling can stress the memory more. As for fans make
sure you have good air flow through the case, especially with more
recent CPU's.
> I might build a new kernel to see if that solves the problem.
It's always good to make sure your up to date, especially on the driver
front but it's usually bad to do the insmod -f. The structures used
within the kernel can be configured differently from how the module was
built.  Some it may not matter but others can be a problem.

for live your not re-encoding, you do want encode so that an ogg vorbis
stream is produced but it looks like downmix and resample are not
needed.

I rebooted the system without loading the pwc and pwcx modules. Still the same 
problem on starting ices live.

But the kernel messages and the output of lsmod now say: 
Tainted: P
instead of 'PF'.

So that would mean there are more tainted modules. By the way, what do the
'P'
and 'F' mean. Nothing is said about this in the lsmod manpage.
I might try rebooting the machine without any module loading.

Well I downloaded and burned the bootable memtest86 cd. Started the system. I 
left it running the (standard) test for more than 3 hours (4 passes): no 
errors. So the memory seems to be OK.

I don' t know if it is useful but I included a dmesg after the last boot 
(again with the pwc and pwcx modules loading). This is the Slackware 8.1 
distibution adaptec scsi kernel.
