lighttpd issues with glibc after update

[lama]

Hello guys,

after updating my raspberry pi i encountered problems restarting lighttpd. I am not sure why this problem appears.

The output of systemctl status lighttpd is:

Dez 25 23:12:38 cloudheim lighttpd-angel[302]: /usr/bin/php-cgi: relocation error: /usr/bin/php-cgi: symbol , version GLIBC_2.4 not defined in file libc.so.6 with link time reference
Dez 25 23:12:38 cloudheim lighttpd-angel[302]: lighttpd-angel.c.139: child (pid=303) exited normally with exitcode: 255

The lighttpd error.log says:
2014-12-25 22:58:34: (mod_fastcgi.c.2838) ERROR: spawning fcgi failed.
2014-12-25 22:58:34: (mod_fastcgi.c.1754) connect failed: Connection refused on unix:/tmp/php.socket-0

If this is PHP on Gentoo, add 'fastcgi' to the USE flags.

fcgi is installed and lighttpd is configured to use it. It worked until the update. Any idea, what this problem is about? Or is this a bug i should report?

Was this after a full Syu and a reboot?

Yes.
