Hello all, We are facing frequent issues of varnish unresponsiveness for sometime on our production server.
During this time we have seen that pz_list is being increased to ~3000 and recv_queue is increased to ~130 Also, varnish is responding with response code '0' for sometime, which meant unresponsive. This is causing multiple 5xx on front ends. FYR: User request count during this time is normal. Note: During this time, we have confirmed that our backend servers are healthy without any issues. May I know what could be the reason for this behaviour at varnish? Please give me the direction on how to debug this issue.
