-- The VM has limited space
-- You're getting a filesystem full error message
-- A log file has gotten ridiculously large (1.5GB in my case)

Solutions:
-- Backup, remove, and recreate the files
-- Backup and use the built in tool: truncate
-- Delete everything.
Let's do it:
the filesystem full error message will tell you which filesystem is full, to view details about your other filesystems use the df command
%df -h

/dev/ad0s1a 496M 64M 392M 14% /
devfs 1.0K 1.0K 0B 100% /dev

/dev/ad0s1d 1.9G 1.8G -2.8M 100% /var
Looks like our /var directory is full. There are few things, that I know of, that would grow and cause this directory to fill; the log files.
use the cd command to cd to the directory the logs are located at
%cd /var/log/
use the list command with the proper flags to view files and their human-readable sizes
%ls -alh

Looks like we have some pretty large files there, the G means gigabytes and the M means megabytes. While it is generally believed that bigger is better this is a bit much.
We can either delete these two files and recreate them or shave off some of the extra fluff.
Take a quick look at the manual page for truncate. Then put on your robe and wizard's hat. Once you're set You can speak the magic words:
truncate -c -s -900m httpd-access.log
And this should chop your file down a fair bit. You can keep using this command and modify the number until you get the file down to what you feel is a reasonable size.
%ls -alh

All that's left now is to take off the robe and wizard's hat....and put it all away...
