Hi!

Yesterday one of our haproxies (1.8.5) with nbthread=8 set in its config stuck with 800% CPU usage. Some responses were served successfully but many of them just timed out. perf top showed this:
  59.19%  [.] thread_enter_sync
  32.68%  [.] fwrr_get_next_server


Hi,

Could you share your configuration please ? It will help to diagnose the problem. In your logs, what is the values of srv_queue and backend_queue fields ?

Thanks,
