Dear PHP user, the update from php-apc to Version 3.0.17 includes a security fix: http://nvd.nist.gov/nvd.cfm?cvename=CVE-2008-1488 But it seems that the other changes of that new version are introducing several problems which will cause php to crash. It seems to be quite random but I have seen phpMyAdmin triggering those crashes a lot. I would recommend to disable APC until this is fixed. My current plan is to downgrade APC to 3.0.16 again and try to backport the security patch only. Greetings, Pierre PS: this bug-report seems to be related: http://pecl.php.net/bugs/bug.php?id=13505 -- archlinux.de
