Entropy is used to calculate random data that is used by the system in cryptographic
operations. Some environments with low entropy may have intermittent performance issues
with SSL-based communication. This is more typical on virtual machines, but can occur in
physical instances as well. Monitor the kernel.random.entropy_avail
in
sysctl
value for best results.
If necessary, update $JAVA_HOME/jre/lib/security/java.security
to use
file:/dev/./urandom
for the securerandom.source
property.
