If you slightly organize your SQL, it looks rather peculiar to me:
SELECT stat_day, obs_day, stat_week, obs_week, NULL AS stat_cputotal,
+
stat_memfree, stat_md5, stat_month, obs_month, stat_type,

In general, your use of parenthesis looks odd, but the statement that looks off is:
select * from (mem_stat NATURAL LEFT OUTER JOIN host )
I'd leave the parenthesis off this one. In general, to debug something ugly like this, I like to start from the inside out and verify the sql. You don't need all the columns and such.
So first, I'd try in the sqlite3 shell:
select * from (mem_stat NATURAL LEFT OUTER JOIN host )
If that works, then I'd go with:
SELECT stat_qtr, obs_qtr, stat_qtr AS cus_qtr, stat_qtr AS crash_qtr,
MIN(stat_memfree) AS stat_memfree
FROM (
<<<previous statement after it works>>>
)
(As I said, for debugging you don't need to have all columns, at least at first.) Next, I would try:
<<<previous statement after it works>>>
GROUP BY stat_qtr
Then, piece by piece, rebuild your statement. When it fails, you know which small piece to look at. Fix that piece and continue until you've rebuilt the statement. Generally, I add most of the columns toward the end, as I find that columns are the things I rarely have trouble with.
If I had to guess, your odd use of parenthesis is the problem.
