Chia Network has just released version 1.2.6 of their Chia Blockchain software. This version of the software fixes a critical memory leak that has been plaguing farmers and forcing them to restart the application regularly. This memory leak has also been attributed to part of the problem with the Bluebox Timelords that forced Chia to turn off the expanded cluster and pause the process of compressing the blockchain.
Also fixed is the invalid plot problem when copying plots from one monitored folder to another, something that has plagued farmers from the beginning.
The following are the actually quite significant changes from the release notes. But really you should go upgrade. Your client crashing is not going to help rewards.
