v9.16 test failure in Perflab: uv_udp_init_ex() errors out
Version
Affects v9.16 : Since !5717 (merged) was merged.
Symptom
Perflab test config LTT/v9_16/recursive/NXD-medium/dnsgen started failing.
named
errors out before the test even starts with message:
udp.c:226: fatal error: RUNTIME_CHECK(r == 0) failed
Example of an affected run: https://perflab.isc.org/#/run/test/61f911b58d88f33170df08b6/
Additional info
Surprisingly, other test configurations do not seem to be affected, not even on v9_16 branch.
In any case, this is very suspicious and needs investigation ASAP before we tag %February 2022 (9.16.26, 9.16.26-S1). It stopped working during this monthly cycle so if it is a bug then it is a regression.
