There's a known goroutine leakage in 1.4.4. You may need to apply this patchset.

During our performance tests, we noticed that, both peers’ and orderers’ memory usage is increasing under load and they do not release the claimed memory when the load is removed.


Is this expected? Anything we can do about it on the configuration side?


Peers: Up to 15G -> This is especially very high

Orderers: Up to 4G


Fabric version: 1.4.4
