Background

Hardware (e.g. network cards) or the operating system can corrupt data during communication. This can lead to unexpected system behavior and failures.

Improvement

Use checksums to detect data corruption during the communication between cluster nodes. This can detect problems caused by the hardware or the operating system. It also can detect some bugs in our communication code. Using checksums reduces the risk of undetected data corruption during communication.
