A real problem requiring thought this early Sunday morning...  And before 
coffee...  Lets start with definitions.  That may also get my thoughts 
straight.

/dev/md0c is your ram disk.  It is statically created at boot.  It does not 
grow.  It holds leases, databases, arp tables, log files...  Something has 
you full.  128 is enough ram, but the files system is 11 meg whatever you 
have. Lets start with what services are you running?  How long are your 
logs? (Over 50 takes space fast)  Do you have a complex captive portal page 
with a lot of images?

/dev/ad0a is your drive image. (Hard drive or CF)  The image size is also 
static, so Andrew is confused. :-)  The important thing is that nothing is 
saved here.  The only time this is opened for writing is to save the 
config.xml or to upgrade firmware.

So look at your log files.  Also look around your file system at /var/log 
and see what is big.  Nothing there should be over 256k.
