MMapDirectory - Mapping Failed error

[deniz <de...@gmail.com>]

Hi All,

I was testing my solr on MMapDirectory, and while indexing, I get this error
lines in the log:

And this is how i run the start.jar file:

/java64/bin/java \
-server \
-XX:+UnlockExperimentalVMOptions \
-XX:+UseG1GC \
-XX:+UseCompressedStrings \
-d64 \
-Xmx4096m \
-jar start.jar &

As another fact, on the interface, it shows success for indexing... so this
error lines simply informative about something not important? 

anyone knows why i get this error? I am running on a 64-bit linux OS with
solr 4.0..
