Warning: Available entropy is low. As a result, use of the UUIDField, SSL, or any other features that require
RNG might not work properly. To check for the amount of available entropy, use 'cat /proc/sys/kernel/random/entropy_avail'.

NOTE: Please install lsof as this script needs it to determine if Solr is listening on port 8983.
