[oe] Question on apr on what it said during build

[J. L.]

I am building a image and had apr error out while building so I did a
-c clean and rebuilt it which it did fine but, I saw something I had
not noticed before and would like to know if its something to worry
about and if its not what does it mean. The message is below:

NOTE: Running task 749 of 759 (ID: 13,
/home/vdubhack/overo-oe/org.openembedded.dev/recipes/apr/apr_1.3.5.bb,
do_package)
