We currently got problems using eAccelerator together with suhosin patch.
If Suhosin and eA are enabled and apache is running a few hours, suhosin detects some Errors:
ALERT - canary mismatch on efree() - heap overflow detected (attacker '89.55.*.*', file '/var/www/virtual/forum_new/lib/page/BoardPage.class.php', line 180), referer: http://diginights.com/forum/index.php?page=Index
if only eA is enabled, the apache simple segfaults an exits.
if suhosin is enabled and eA disabled, everything works fine, but without eA, the thing makes no sense :(
For the user this effect is shown with completely white PHP Sites.
Our System:
Debian Etch
Kernel 2.6.22-3-amd64
PHP 5.2.5-2 with Suhosin-Patch 0.9.6.2
eA stable Release-0.9.5.2
Used PHP Software is Woltlab Burning Board. (http://woltlab.com)
any ideas?
thx
