[14:33:50] Please set system property '-Djava.net.preferIPv4Stack=true' to avoid possible problems in mixed environments.
[14:33:50] Initial heap size is 30MB (should be no less than 512MB, use -Xms512m -Xmx512m).

[14:33:50] Message queue limit is set to 0 which may lead to potential OOMEs when running cache operations in FULL_ASYNC or PRIMARY_SYNC modes due to message queues growth on sender and receiver sides.
