With the latest two PHP updates, some users reported problems with FPM, with APC, etc… It was about segfaults, problematic init scripts, and so on… But all those comments couldn’t really help me to diagnose the problems in an efficient manner.
Here are the pieces of information that you have to provide to help me fixing your problem :
- What is your distribution? (disclaimer : only Debian stable is supported)
- What is your architecture? amd64 or i386?
- Which exact PHP version are you using? 5.4.x or 5.3.x?
- Which SAPI are you using? mod_php? CGI? FPM? Embed?
- What’s the full content of your
/etc/apt/sources.listand/etc/apt/sources.list.dfiles? - What is the result of
dpkg -l 'php*' | grep '^.i'? - Please provide a textual description of the bug (don’t hesitate to provide some code, the expected result…).
- Please provide any modified configuration directive.
- Please provide a backtrace, after installing
php5-dbg.
Now, some tips to have a stable PHP stack :
- Only use PHP packages from Dotdeb when possible.
- Be sure to upgrade them to the latest version.
- Uninstall
php5-suhosinif you don’t use it explicitly. The development of this extension has kinda been “stalled”. - If you have problems with extensions, deactivate and reactivate them one by one to find the guilty one.
Because blog comments are not the best place to report issues, Dotdeb uses the Github bugtracker for now. Be sure to follow the above instructions, to read the official PHP bug tracker and also the existing Dotdeb bug reports before submitting any new issue.
Improving the overall stability of the Dotdeb packages requires efforts from us all. Thanks in advance for your help.
I get errors with APC too. Here is my actual apc.ini :
extension=apc.so apc.enabled=1 apc.enable_cli = 1 apc.num_files_hint = 1024 apc.shm_segments=1 apc.shm_size=512M apc.ttl=3600 apc.user_ttl=3600 apc.filters=apc.php
When I disable APC or if I remove apc.filters=apc.php I don’t get any error.
Hope it could help.
@moog : did you run this command and restart FPM / Apache / … ?
I had a lot of problems related to APC since the last update, a lot of SegFaults with the APC cache method for the db queries of PHPBB for instance. I disabled that, and still had SegFaults with a simple upload progress that uses APC. But I didn’t reinstall PHP-APC the way you indicate here. Now that i did, hopefully, the bugs will be gone.
Anyway, even with that latest bugs (that pissed me off, of course), I want to thank you for your very, very, very useful work. I mean it. I love debian and its stability but I almost always need the latest version of PHP and without you, i’d be almost completely lost. I wanted to thank you for a long time, now’s the occasion :-)
I’m having the same problem with php-apc. Tried reinstalling, purging and even reinstalling everything related to PHP. It keeps segfaulting if apc is installed but if not, everything works just fine. Where should I start?

@Toni Lähdekorpi : first read the above blog and follow the different steps, including providing a backtrace and report useful bug reports (or contribute to existing ones).
Also make sure that the following line is present in /etc/init.d/php5-fpm :
FYI APC 3.1.12 from Dotdeb is the same as the official APC 3.1.13
I need APC for my Magento setup. Also:
