Hello everyone,
I'm trying to parse a large number of small reports for some data and I'm
doing this by repeatedly calling the following function (with a for) on
each of the files:
(defn get-rep [file]
(let [report (with-open [rdr (io/reader file)](*slurp rdr*))
reg #";\s+(\d+\.\d+) \s+; (\d+\.\d+) \s+;"
match (re-matcher reg report)
found (re-find match)
fmax-85c (second found)
rfmax-85c (nth found 2)
found2 (re-find match)
fmax-0c (second found2)
rfmax-0c (nth found2 2)]
{:fmax-85c fmax-85c
:rfmax-85c rfmax-85c
:fmax-0c fmax-0c
:rfmax-0c rfmax-0c}))
My problem is that after a while my program crashes with a jvm heap error,
it crashes on the slurp line (in bold), although that probably doesn't mean
much. The slurp line is the only one that I suspect since it's the biggest
memory consumer in my program.
Now I'm wondering what's going on and why don't the report files get freed
from memory. I'm suspecting this might be caused by lazyness at some level,
but I can't figure out where. Any ideas?
Thanks!
