In my WebHostManager, I see this:

----------------------------------------------------------
Service Status

apache up
cppop up
exim up
interchange up
mysql up
proftpd up
Server Load 2.36 (2 cpus)
Memory Used 27.1 %
Swap 0.943 %
Disk /sda9 (/) 46 %
Disk /sdb1 (/backup) 15 %
Disk /sda1 (/boot) 24 %
Disk /sda10 (/home) 12 %
Disk /sda8 (/tmp) 100 %
Disk /sda5 (/usr) 35 %
Disk /sda6 (/var) 19 %
-------------------------------------------------------------

"Server Load" and "Disc /sda8" are both flashing red. I'm told by several people my site is down, but I can still access it ( www.talkingpresents.com ). How do I interpret the data above? I'd also appreciate if you could tell me if you can access the site.

Your site works for me

Are you using mod_gzip?
If so, try to clean the /tmp folder of all the mod_gzip temporary files.
