On the subject of rising memory consumption, if you are using a tmpfs 
mount on /tmp, that might explain part of it.

On the increasing load: can I suggest that you take regular snapshots of 
files that contain statistical info (e.g. /proc/interrupts, 
/proc/meminfo) and see if that turns up any useful leads.

Another thing: if you are using CPU frequency scaling (as I am) then the 
CPU load can vary in strange ways. For example, if you're using the 
ondemand governor and are not allowing niced processes to crank the CPU 
up to full speed, then these processes will consume a higher percentage 
of CPU time than when they run in the presence of a non-niced process 
(even if the latter itself consumes very little CPU).

This would not explain a steady increase in CPU load, but might confuse 
you enough into believing that it does.

Clasping at straws here, but hope it helps.

Cheers, Jan
