Hi Ilya, Willy,

PiBa, how many CPU cores are you running ?
it turned out that I run tests on very low vm, which only has 1 core.
and tests pass.
cirrus-ci as far as I remember do have many cores.
I was running with 16 cores..
can you find single core vm ?
Well, i reconfigured the VM to have 1 core, but same issue seems to show
up, though not on every time the test is run, and actually a bit less
often..
Below some additional testresults with different kqueue / vCPU settings..
*VM with 1 vCPU*
Running: ./vtest/VTest-master/vtest -Dno-htx=no -l -k -b 50M -t 5 -n 20
./work/haproxy-08fa16e/reg-tests/compression/lua_validation.vtc
Results in: 4 tests failed, 0 tests skipped, 16 tests passed
Adding "nokqueue" in the vtc file i get:
8 tests failed, 0 tests skipped, 12 tests passed
4 tests failed, 0 tests skipped, 16 tests passed
So its a bit random, but the 'nokqueue' directive does not seem to
affect results much..
*With 16 vCPU*
Without nokqueue: 16 tests failed, 0 tests skipped, 4 tests passed
With nokqueue (using poll): 17 tests failed, 0 tests skipped, 3 tests passed
The failure rate seems certainly higher with many cores..
* Using commit 0eae632 it works OK*
Just to be sure i re-tested on 16 cores with 2.2-dev0-0eae632 but that
does nicely pass: 0 tests failed, 0 tests skipped, 20 tests passed
Regards,
PiBa-NL (Pieter)
