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