What I did
Backported sonic-net/sonic-swss#4319 to the
202412branch.This keeps the async actor loop fixes for
countersyncd, including the follow-up thread-spawn and shutdown handling adjustments.Why I did it
The 202412 line needs the same fixes so
countersyncdavoids blocking async actor loops and handles the SWSS reader thread lifecycle more safely.How I verified it
Backport was validated as part of the combined 202412
countersyncdstack verification.A merged 202412 build containing the backports of public PRs 4316/4317/4318/4319 was built and deployed to DUT
str4-sn5640-2, then the full HFT regression was run:high_frequency_telemetry/test_high_frequency_telemetry.pytests=14,failures=0,errors=0,skipped=720241212.54Details if related
