Apache/2.2.9 Segmentation fault (11)

Sziasztok

Van nekem egy apache webszerverem, amit http proxynak használok. Nincs betöltve semmilyen extrame modul, sem php, sem hasonló hogy a fent megjelölt [Segmentation fault (11)] hibát mondjuk egy hibás php script generálja. A logban ez látható:

Volt már valakinek ilyen hibához szerencséje? A fő probléma nem a figyelmeztetés a logban hiszen a webszerver megy ettől függetlenül, hanem az, hogy beragad ettől 3-4 httpd process és 100%-on zabálja a cpu-t. A htop-ban a process elött pirossal ki van emelve az időpont, ez nem tudom mit tesz, de biztos nem normális.A apache forrásból lett lefordítva.

Szerk: Idő közben megtaláltam a választ. Memória hibára utal a dolog. Lehet ez egy apache bug vagy tényleg hardware hiba? Nem egy gagyi szerverről van szó, sun szerver.
