[Bug 1581864] Re: nginx.service: Failed to read PID from file /run/nginx.pid: Invalid argument
Hi, I'm closing the Xenial task because it reached EOSS (End of Standard Support) so I'm afraid it can't be fixed (and this is not a security bug). The bug is still present in Bionic because it is the only supported series without the patch (nginx-fix-pidfile.patch).

[Bug 1581864] Re: nginx.service: Failed to read PID from file /run/nginx.pid: Invalid argument
I've developed and tested a different approach. More invasive and probably not something upstream will like the look of! The approach is to have ngx_daemon() not do the parent process exit() after fork() but to return the child PID. The parent process detects that (a value > 0), sets ngx_pid = child_pid, calls ngx_crate_pidfile(), then does the exit().

[Bug 1581864] Re: nginx.service: Failed to read PID from file /run/nginx.pid: Invalid argument
This may be a viable workaround. For a systemd Type=fork unit 'success' is determined when the parent process exits. At this time systemd expects the PIDFile to exist. nginx actually creates the PID file in the forked process. Presumably on single CPU systems there is a sufficient delay in scheduling for the forked process not to have created the PID file when systemd checks for it. Bring the creation of the PID file forward into the parent process. ** Patch added: "Bring PID creation into parent process" https://bugs.launchpad.net/ubuntu/+source/nginx/+bug/1581864/+attachment/5268127/+files/nginx-pid-race.patch -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1581864 Title: nginx.service: Failed to read PID from file /run/nginx.pid: Invalid argument To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nginx/+bug/1581864/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1581864] Re: nginx.service: Failed to read PID from file /run/nginx.pid: Invalid argument
Hi, We are also affected, and I've looked into the source. In main(), the ngx_create_pidfile() gets called right after the ngx_daemon() function. ngx_daemon of course forks, and the parent process exits immediately with exit(0). This is a pure race condition between nginx and systemd. This is not a problem (other than the scary log), because the PIDFile option is not needed for determining the main PID of nginx (systemd can correctly "guess" the main pid), it's only for removing the file when the service exits. As far as I can tell, this daemonization is not needed for the systemd service use-case. The service should be Type=simple, and 'daemon off'. The standard file handles get redirected by systemd anyway, and non-stop upgrade cannot be used in this case either. (See: http://nginx.org/en/docs/faq/daemon_master_process_off.html ) If this is too much of a change, another workaround is removing the PIDFile option, and adding the line: ExecStopPost=/bin/rm -f /run/nginx.pid Regards, Alex -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1581864 Title: nginx.service: Failed to read PID from file /run/nginx.pid: Invalid argument To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nginx/+bug/1581864/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
