Description:
------------
openSUSE 12.1 (Asparagus) (x86_64) with packages:
 - php5-5.3.8-4.34.1
 - apache2-mod_php5-5.3.8-4.34.1
 - php5-devel-5.3.8-4.34.1
 - php5-pear-5.3.8-4.34.1
Used PECL to build and install APC-3.1.13. (but it happend with 3.1.8 also before).

These are the latest updates. When suddenly:
[Wed Dec 05 17:00:02 2012] [notice] SIGHUP received.  Attempting to restart
httpd2-prefork: Could not reliably determine the server's fully qualified domain name, using 10.x.x.x for ServerName
[Wed Dec 05 17:00:03 2012] [notice] Apache/2.2.21 (Linux/SUSE) mod_ssl/2.2.21 OpenSSL/1.0.0e configured -- resuming normal operations

[Wed Dec 05 17:10:44 2012] [error] [client 10.x.x.y] PHP Fatal error:  apc_fetch() [<a href='function.apc-fetch'>function.apc-fetch</a>]: unable to obtain pthread lock (EDEADLK) in /srv/www/htdocs/cc/include/SugarCache/SugarCacheAPC.php on line 80


This reload (/etc/init.d/apache2 check-reload, /etc/init.d/apache2 reload) was initied by logrotate.

After this error, all PHP-Scripts requiring this class (SugarCacheAPC) won't load until a request-timeout. No further errors appear in the error_log. An Apache-restart solves the issue.

extension=apc.so

Any chance to get some repro code from that SugarCacheAPC.php?

Also you've set php version to irrelevant, but use 5.3 in the example. Sure it happens also with newer PHPs?
