webserver asks me to download file?

[Ben Adams]

Hello,

I have just created: www.BSDWorld.NET
I'm running FreeBSD 7.0 amd64
apache-1.3.41
php5-5.2.6

When I load any page sometimes it asks me to download the php file. (but 
only client side view)
nothing in apache error log.

If my router speed matters, it's not fast I maybe maxing it out for 
throughput.

Also ram will also never free up: (have to reboot to free the ram)
last pid:  2420;  load averages:  0.00,  0.00,  0.00    up 0+02:48:12  
13:36:06
63 processes:  1 running, 62 sleeping
CPU states:  0.0% user,  0.0% nice,  0.0% system,  0.1% interrupt, 99.9% 
idle
Mem: 54M Active, 3417M Inact, 312M Wired, 316K Cache, 214M Buf, 4130M Free
Swap: 4096M Total, 4096M Free


Thanks for any help to this.
