APC : fatal bug

I've believed for one day I've finally found an opcode cache which work on my system (because I had many problems with eaccelerator) but it's still not the case. It seemed to be fine for 22 hours but just 30mn ago, problems began. It resulted on crashes for many php (cached) pages (including acp.php, so that I haven't many details about the state of apc) but some cached pages were still working. My logs looked like : " [Fri Aug 19 22:10:49 2005] [notice] child pid 3519 exit signal Segmentation fault (11) [Fri Aug 19 22:10:50 2005] [notice] child pid 3399 exit signal Segmentation fault (11) [Fri Aug 19 22:10:50 2005] [notice] child pid 3445 exit signal Segmentation fault (11) [Fri Aug 19 22:10:50 2005] [notice] child pid 3449 exit signal Segmentation fault (11) [Fri Aug 19 22:10:50 2005] [notice] child pid 3459 exit signal Segmentation fault (11) [Fri Aug 19 22:10:50 2005] [notice] child pid 3514 exit signal Segmentation fault (11) [Fri Aug 19 22:10:51 2005] [notice] child pid 3385 exit signal Segmentation fault (11) [Fri Aug 19 22:10:51 2005] [notice] child pid 3456 exit signal Segmentation fault (11) [Fri Aug 19 22:10:52 2005] [notice] child pid 3440 exit signal Segmentation fault (11) [Fri Aug 19 22:10:52 2005] [notice] child pid 3452 exit signal Segmentation fault (11) [Fri Aug 19 22:10:52 2005] [notice] child pid 3453 exit signal Segmentation fault (11) [Fri Aug 19 22:10:52 2005] [notice] child pid 3500 exit signal Segmentation fault (11) [Fri Aug 19 22:10:52 2005] [notice] child pid 3504 exit signal Segmentation fault (11) [Fri Aug 19 22:10:52 2005] [notice] child pid 3521 exit signal Segmentation fault (11) free(): invalid pointer 0x899211!
