Problems with trailing 0 in URI
Added by mdurrant over 13 years ago
I've been having a weird problem with 1.4.28.
Any URL that ends with a trailing 0 causes lighttpd to crash completely, alternating between a 500 and 503 error every few refreshes.
For example:
example.com/index.php (works fine)
example.com/index.php/news/672 (works fine)
example.com/index.php/news/6720 (crashes)
2011-03-01 17:47:41: (mod_fastcgi.c.2906) establishing connection failed: Connection refused socket: tcp:127.0.0.1:9999
2011-03-01 17:47:41: (mod_fastcgi.c.2912) backend is overloaded; we'll disable it for 1 seconds and send the request to another backend instead: reconnects: 0 load: 1
2011-03-01 17:47:43: (mod_fastcgi.c.3597) all handlers for /0? on 0 are down.
2011-03-01 17:47:43: (mod_fastcgi.c.2854) fcgi-server re-enabled: tcp:127.0.0.1:9999
I am using lighttpd with the only modules enabled that aren't on by default being mod_evasive, mod_rewrite, fastcgi and simple_vhost. I have confirmed that it is a mod_fastcgi issue, but I'm not sure how to troubleshoot it.

That's not a crash of Lighttpd.
Looks like a crash of PHP.

I've got exactly the same problem with drupal (6.20) lua for clean urls and php53 on Scientific Linux (5.5) 32Bit.
Everything's working fine except for urls containing a trailing "0" (Zero)
Here is the error.log

This is very strange, maybe this is an php error ... nevertheless ... maybe so can help us out here?

We do have the same problem here for:
- php v5.2.14-0.7.22.1
- lighttpd v1.4.28-2.5
- SLES 11 SP1 i586

any ideas?

- just enabling example configs is never a good idea. understand what they do, and use what you need.
- somehow the configs resulted in a fastcgi.server with extension key "0" (so it triggers on all urls with trailing "0"); this is the case if you omit the extension ".php" => like fastcgi.server = ( ( ... ) ) - if someone can provide an example where this happens in other cases i'd like to see the config.

I had a similar problem running Lighttpd, PHP and CodeIgniter with url rewrites like everyone else.
If you look in your conf.d folder, and open up fastcgi.conf, youll probably have a line
fastcgi.server = ( ".php" =>...
Well, this says if the URL ends .php, then carry out these instructions ....
So we bluff it adding the line
fastcgi.map-extensions = ( "" => ".php" )
N.B.
This will map all extensions to .php, this includes your CSS, JS files etc.
On my server, I host these files on a different server, and didn't have any problems, but if you host it all on the same server, the browser wont render your files properly.
