  • [ ] test_cluster_migration_while_seeding
  • [ ] test_denyoom_commands

For test_big_containers it would almost never finish because of a bug within the epoll socket (https://github.com/romange/helio/pull/363). After the fix, locally the memory does not surpass 1.4x (dropped from 2x) but it seems that on the CI it still fails with (2x). I also:

  • compared the INFO MEMORY from both EPOLL and IOURING leading to very similar memory footprints for both variants
  • calculated the total allocations and deallocations with the memory tracker for both EPOLL and IOURING and both of them had very similar results

I suspect there is something around the EPOLL socket operations that "wastes" memory but we need to somehow narrow it down

Curiously the segfault was in pytest, so might not be an issue with dragonfly but the pytest setup:

Fatal Python error: Segmentation fault
