Subject: php5-fpm startup process crashy since 5.4.4-rc2

Date: Sun, 10 Jun 2012 23:05:36 +0200

Package: php5-fpm
Version: 5.4.4~rc2-1
Severity: important

The php5 FPM SAPI does not reliably start up for me after 5.4.4~rc2-1 migrated to testing and landed on my system.
It will randomly lock up during startup, just after it has started its worker processes and should be exiting.
This makes the php5-fpm init script lock up also of course.

When in this wedged state it will not respond to a SIGTERM anymore, you have to SIGKILL it. Attaching strace to
the hung process indicates it is locking on some futex() call:
futex(0x7fe3a4215e60, FUTEX_WAIT_PRIVATE, 2, NULL

It seems to be timing related, as 1) its random, 2) running it under strace or gdb makes all sorts of things
happen randomly.

5.3.3-6 from snapshots does not show this behaviour.

Also I noticed the 5.4.4~rc2-1 php reports version 5.4.5-dev. Hum.

No odd modules enabled, only -gd, -imap, -mcrypt and -mysql

[Message part 1 (text/plain, inline)]

Even though our configuration is different (we are using a 5.4.5-1~dotdeb.0
build of php5-fpm on Ubuntu 12.04 LTS that has been upgraded from previous
LTS releases), we have been encountering this identical hang issue, same
syscall, and other symptoms.

We were able to temporarily address the issue by removing the php5-imap
module from our environment, so this looks like it could be a result of
dependency issue.  Happy to contribute if we find out more.

thank you

Andre & Anthony,

I have pulled some fix for crasher bug into 5.4.4-4, could you please
try with that version?

And if that doesn't help, could you please try with 5.4.6-1 from
experimental, the fpm SAPI got several updates?

Also if nothing helps, it's probably upstream bug and worth reporting
to bugs.php.net (I could do it for you, but it's usually better if the
person who experiences the crash do the report and adds to URL here.)

Hmm, it definitely looks like an upstream issue. Would you be willing
to report that
to bugs.php.net, please?

Subject: 5.4.6 issues, also drupal7 weirdness

Date: Thu, 06 Sep 2012 14:21:50 -0400

Additional data points that may or may not be related:

For all of the following, the host system is sid i386.

I'm having Drupal7 weirdness since applying updates and ending up at (I
think) 5.4.4-7 on 8/22.  Drupal is at 7.14-1.  This setup runs under
nginx.  The error logs look like this:

Sep  5 15:31:56 www ool www: PHP Fatal error:  Call to undefined function <B0>K() in /usr/share/drupal7/index.php on line 17
Sep  5 15:31:57 www ool www: PHP Fatal error:  Call to undefined function <B0>K() in /usr/share/drupal7/index.php on line 17
Sep  5 15:32:05 www ool www: PHP Fatal error:  Call to undefined function (^N0BԂ
<9D>@() in /usr/share/drupal7/includes/bootstrap.inc on line 11
Sep  5 15:32:15 www ool www: PHP Fatal error:  Call to undefined function <B0>K() in /usr/share/drupal7/index.php on line 17

Note the control characters instead of actual function names, and that
they change from request to request.  A 500 is returned to the client.

I'm also having weirdness with Apache (2.2.22-11, mod-php loaded) not
stopping when asked, where the master process locks up and can only be
killed -9.  This doesn't occur every time.

====

So with this bug and the above as context, and knowing that surgery is
in progress to adapt to php4, prepare for apache 2.4, etc, I tried the
5.4.6 packages from experimental.

After applying the experimental packages, mod-php under apache
(mpm-prefork) sometimes (some workers, maybe?) throws errors similar to
the ones above, with garbage in the logged errors.  I also saw fpm hang
at startup a few times with
5.4.6.

I've gone back to all-sid packages for now, as this is a production
machine.

====

Sorry this is so disorganized.  Not sure what bits are relevant, and
what might belong in a different bug report.
