Lately, in one of my busiest locations, we've started seeing a strange issue when SmP stops responding on 8443 for API calls. The process itself is running, logs messages are logged, just no response from it: [root@spc01 ~]# systemctl start foreman-proxy [root@spc01 ~]# date; curl --connect-timeout 30 -kSs https://localhost:8443/bmc; date Thu Oct 5 17:53:36 MST 2017 curl: (7) Failed connect to localhost:8443; Connection refused Thu Oct 5 17:53:36 MST 2017 It does take ~30 seconds to start up in our env because of large DHCP dataset, during which the connection would be refused. [root@spc01 ~]# date; curl --connect-timeout 30 -kSs https://localhost:8443/bmc; date Thu Oct 5 17:53:49 MST 2017 curl: (28) NSS: client certificate not found (nickname not specified) Thu Oct 5 17:54:19 MST 2017 Then it starts working for a very short period of time (above) and then stops (below). [root@spc01 ~]# date; curl --connect-timeout 30 -kSs https://localhost:8443/bmc; date Thu Oct 5 17:54:24 MST 2017 curl: (28) Operation timed out after 30001 milliseconds with 0 out of 0 bytes received Thu Oct 5 17:54:54 MST 2017 So far there's nothing in proxy.log that helps me identify the issue. I can't replicate it at will no matter what I do - had a bunch clients hitting different APIs for a couple of days, nothing. Then today the above happens and the only thing that helped me is to move SmP from one node to another (I really wish DHCP SmP would allow for active/active horizontal scaling instead of just being limited to a single node). Strace is useless as it only give this on tracing "ruby foreman-proxy" process: [root@spc03 ~]# strace -p 12526 strace: Process 12526 attached futex(0x184e634, FUTEX_WAIT_PRIVATE, 1, NULL^Cstrace: Process 12526 detached <detached ...> I tried https://github.com/tmm1/rbtrace, but it is so heavy that it actually pretty much kills SmP by itself. Do you have any suggestions on ways to troubleshoot this? I have DEBUG enabled with these values: :log_buffer: 4000 :log_buffer_errors: 2000 Also, is a way to move SmP from WebBrick to Apache/Passenger if that makes sense at all? If so, any docs? Any other ways to increase the performance as it does feel like a performance issue to me. Thanks! -- You received this message because you are subscribed to the Google Groups "Foreman users" group.
