Hello, we're using varnish v5 (debian stretch) for image caching; yesterday there was a strange outage where i'm somehow unable to find the reason as there are almost no log entries, besides one:
Feb 17 09:03:47 rowlf kernel: [1047133.190149] cgroup: fork rejected by pids controller in /system.slice/varnish.service But the problems started a couple of minutes before that, so this message simply could be a result of previous problems. Some munin graphs: Backend traffic: strange spike in backend connection retry/success, decrease in recycle/reuse: https://abload.de/img/varnish_backend_traffqwj74.png Expunge: a similar spike in "Number of expired objects" https://abload.de/img/varnish_expunge-day5kk0l.png Threads: threads went up at that time; was lower before (restart was done on Feb 14th), and suddenly went up. day: https://abload.de/img/varnish_threads-dayzoken.png week: https://abload.de/img/varnish_threads-week7qjoo.png Backend graph: https://abload.de/img/nginx_status-day54jkd.png /etc/systemd/system/varnish.service : https://pastebin.com/aAhMHn4p Here's the (shortened) vcl file: https://pastebin.com/nVu5vVaa Anyone has an idea how to dig into this? Something horribly wrong in the vcl file? Thx, Hubert _______________________________________________ varnish-misc mailing list [email protected] https://www.varnish-cache.org/lists/mailman/listinfo/varnish-misc
