1 month ago This is considered a data racing bug. Trying to unlock a pipe Somehow which is already being finit. Recently We pushed some fixes to 0.22.5 regarding the similar case. Could you try both 0.22.5 and previous 0.21.10 to verify the bug scope?
Describe the bug While running nanomq v0.22.2-4 on arm64 platform a log of an error indicating a bug.
Expected behavior No bug message.
