Hi Lukas,
starting from around 200mbit/s in&out, haproxy processes (nbproc 6) are hitting
100% cpu regularly (noticed up to 3 processes at the same time with 100%), but
recover again on its own after some time.
stracing such a process yesterday showed the following:
epoll_wait(0, {}, 200, 0) = 0
epoll_wait(0, {}, 200, 0) = 0
epoll_wait(0, {}, 200, 0) = 0
epoll_wait(0, {}, 200, 0) = 0
epoll_wait(0, {}, 200, 0) = 0
Unfortunately I can't do any more debugging in this setup. HAproxy 1.5.14 is
never near to 10% cpu usage with way higher bandwidth.
Bye,
Sebastian
