[Bug 1242376] Re: reload php5-fpm crashes
I have documented the workaround in the bug description. This bug presumably does not affect releases = Vivid since it is related to upstart and Ubuntu runs systemd since Vivid. So marking Fix Released and creating a Trusty task in case someone can come up with a good fix for Trusty that can be SRU'd. Importance - Medium as a workaround is available. ** Description changed: + [Impact] + + On releases running upstart (those older than Vivid), the php5-fpm + service crashes on reload. + + [Workaround] + + Create /etc/init/php5-fpm.override and add the line reload signal + SIGUSR2 to it. + + [Original Description] + reload php5-fpm with upstart does not work. php5-fpm will crash and leave non-working child processes hanging around that will block any recovery until they are killed off manually. This is because php5-fpm does not handle SIGHUP. It results in an uncontrolled exit. After telling upstart to instead use SIGUSR2 on reload*, things work as expected. * reload signal SIGUSR2 in upstart php5-fpm.conf Signals handled by php5-fpm seems to be: * SIGINT, SIGTERM: immediate termination * SIGQUIT: graceful stop * SIGUSR1: re-open log file * SIGUSR2: graceful reload of all workers + reload of fpm conf/binary Ubuntu 13.10, amd64 ii php5-fpm 5.5.3+dfsg-1ubuntu2 amd64server-side, HTML-embedded scripting language (FPM-CGI binary) ** Changed in: php5 (Ubuntu) Assignee: Pratiksha (deekshammhs10) = (unassigned) ** Changed in: php5 (Ubuntu) Status: Confirmed = Fix Released ** Also affects: php5 (Ubuntu Trusty) Importance: Undecided Status: New ** Changed in: php5 (Ubuntu Trusty) Status: New = Triaged ** Changed in: php5 (Ubuntu Trusty) Importance: Undecided = Medium -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to the bug report. https://bugs.launchpad.net/bugs/1242376 Title: reload php5-fpm crashes To manage notifications about this bug go to: https://bugs.launchpad.net/php/+bug/1242376/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

Any updates on this?

[Bug 1242376] Re: reload php5-fpm crashes
What I just noticed (on an Ubuntu 14.04.4 LTS, using ondrej's PPA) is that /etc/init.d/php5-fpm still exists. When I issue service php5-fpm reload - my FPM engines disappear, even though I have /etc/init/php5-fpm.conf and /etc/init/php5-fpm.override set to enable the reload parameter. Looks like when I run service php5-fpm reload it is trying to hit that (old, outdated) /etc/init.d/php5-fpm script, and wasn't hitting the upstart version. Removed the old init file, and now reload works fine. I am sure there are reasons for leaving it behind (such as if someone isn't using upstart?) but it causes a conflict if left in place. /etc/init.d/php5-fpm might need some additional attention, to read from the same pid files, or whatever (?) if it doesn't get removed soon. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to php5 in Ubuntu. https://bugs.launchpad.net/bugs/1242376 Title: reload php5-fpm crashes To manage notifications about this bug go to: https://bugs.launchpad.net/php/+bug/1242376/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

I have no idea why there's nothing in the logs, but I can say for sure that the PID of the master process *DOES NOT* change between reloads (the execve() call exchange the running code, but not the PID of the process).

[Bug 1242376] Re: reload php5-fpm crashes
I think it's not exactly clear here, why this cannot be fixed right away in Ubuntu 14.04 LTS. The main problem is that 'upstart' is not following Postel's principle (be benevolent in what you receive, and strict in what you send) and barfs and breaks whole release upgrade process if it encounters directive it doesn't know about. In this case the problem gets triggered on upgrades from Ubuntu 12.04 when upstart has been upgraded to 1.12.1, but the PID 1 (/sbin/init) is still binary from upstart 1.5 that fails to start/stop php5-fpm and thus breaking the whole upgrade process. This has by no means an easy fix and only possible solution would be to fix that first in precise upstart to just ignore (print warning) on unknown directives in init files and then fix this in Ubuntu 14.04. Hmm, or we can just patch php5-fpm to reload on SIGHUP :). -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to php5 in Ubuntu. https://bugs.launchpad.net/bugs/1242376 Title: reload php5-fpm crashes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/php5/+bug/1242376/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

Some possible workarounds (off the top of my head): 1) Restart instead. 2) Send a USR2 signal to the correct PID manually (get it with status php5-fpm). 3) Create /etc/init/php5-fpm.override file with the single line reload signal USR2 in it.

[Bug 1242376] Re: reload php5-fpm crashes
+1 We have this issue too. Seems the reload signal USR2 being in the official php5-fpm.conf is still commented out. Not sure why, as it should be able to be pinned just to recent versions of Upstart / releases. I have used Robie's suggestion #3 above in an .override file, and that seems to work at the moment. option #1 isn't really an option (same reasons in comment #15). option #2 is the best bet. Just a little more robustness is required in the Upstart script.

We ran into this bug while upgrading our servers from 12.04 LTS to 14.04 LTS. It is serious for us. When we deploy our app, we need to do `service php5-fpm reload` so that the php opcode cache is flushed, otherwise old files will still be served. Doing a `php5-fpm restart` isn't a option as it does not handle existing connections gracefully. We would really really appreciate for this bug to be fixed in the Ubuntu repos. It is really not a good bug to have in a LTS release for folks who run PHP.

The package 5.5.9+dfsg-1ubuntu3 have the correct upstart script with reload signal USR2, which works great on Ubuntu Trusty since it uses upstart = 1.10.0 For fixing the https://bugs.launchpad.net/ubuntu/+source/php5/+bug/1272788 bug a new package was released, called 5.5.9+dfsg-1ubuntu4, which comments out reload signal USR2.

Hi, We are using Precise LTS too here. The init script from the php-fpm package in Ondřej's php5-oldstable PPA (PHP 5.4) works on Precise. That's using start-stop-daemon instead of upstart. So a fix for Precise, and possibly other older distributions, is to use that init script also on PHP 5.5.
