I build my own rpm's, I do:

export PIE=-fPIE
make LFLAGS=-pie _lib=%{_lib} FULLECHO=

The _lib thing is an rpm macro expansion, which expands to lib64 on my system.

I use the clamav supplied by the fedora project.

I use the RPMForge version of SA-3.3.1.

Same here.

On average we receive about 15000 emails a day per server (2 of them
load balanced), load seems to hover between 1 and 2 during the peaks
of the day. Your load does not seem excessive at all.

It sounds like we have very similar systems. At this point, I think
you should look at how you're building exim.

I also think you should consider that you have some bad memory.
