@afedulov So on my M4 Pro chip MacBook the test starts to run with 11MB consistentlt, and consistently fail with anything under that, since TMs cannot even start because there are not enough resource to allocate for Netty. Since the CI runs on x86 machines, and only fail once in a while, it makes me think CPU architecture matters here and it allocates less memory on a non-ARM architecture. All in all this points me to think we should get away with 12MB for these tests for 1.19 and 1.20. In the meantime I also thought a bit about where that `90mb` memory the backported commit added, and I think they just multiplied the 4M chunk by the task slot number and added some extra margin: `4m x 20 + 10 = 90m`, which is semantically wrong. -- This is an automated message from the Apache Git Service.
