strange memory usage with PAE

Hello I have centos 6 with a pae kernel. When I run free -m I get

free -m
             total       used       free     shared    buffers     cached
Mem:          8019       7614        405        623          1        699
-/+ buffers/cache:       6913       1106
Swap:         7999        474       7525


I am not running any processes but the memory is almost full. Could it be related to my /etc/sysctl.conf

cat /etc/sysctl.conf
net.ipv4.ip_forward=0
kernel.shmmax=4294967295
kernel.msgmax=65536
kernel.msgmnb=65536
net.ipv4.conf.default.rp_filter=1
vm.nr_hugepages=3400
kernel.sysrq=0
net.ipv4.conf.default.accept_source_route=0
kernel.shmall=268435456
kernel.core_uses_pid=1
net.ipv4.tcp_syncookies=1


any ideas thanks

Computer on==running some, often many, processes.

Use ps aux to see what's running and their memory footprints.
Use ipcs -m to see shared mem usage.
