The Director of Technology Product at Lightning Labs, one of the development companies behind the Lightning Network, has pointed out a memory leak bug in the latest Lightning Network Daemon (LND) 0.16.3 release, and is now urging operators not to upgrade or downgrade for those who have. already upgrade their software.
Memory leak bug in LND version 0.16.3
The memory leak flaw detected in LND 0.16.3 could affect the operators of nodes on the Bitcoin Lightning Network, a Layer 2 scaling solution for the world’s most important blockchain, published by Lightning Labs.
This bug causes a memory leak, which over time can put more demand on available memory. This can lead to a gradual increase in the amount of memory used by the program, which can eventually lead to node crashes, affecting operations and, most importantly, reliability.
Thus, the risks associated with this bug may adversely affect the performance and stability of the Lightning Network node, resulting in interruption of transaction processing and entire node operation.

In response to the flaw, the developers advised Lightning Network node operators are holding off upgrading to LND 0.16.3 until remediation is implemented or a stable version is available. Although there are always software issues in complex systems, the seriousness of this particular error requires utmost attention and prompt remediation.
Specifically, it is suggested that those who have already updated to LND version 0.16.3 downgrade to version 0.16.2, which is safe. It may be possible to restore the stability of the Lightning Network node and reduce the risk associated with a memory leak issue by downgrading.
