#23299 [Opn]: Intermittant but reproducable corruption and crash

ID: 23299 Updated by: rasmus@php.net Reported By: bginter at ndevtech dot net Status: Open Bug Type: Reproducible crash Operating System: Linux 2.4.20 PHP Version: 4.3.1, STABLE-200304220130 New Comment: Anything unique about this machine? It's not an IA64 box or anything weird like that, is it? Are you sure your memory is ok and that your cpu is not overheating or something? These crashes look very flaky. For a really good memory checker that catches problems nothing else finds have a look at http://www.memtest86.com/ That probably isn't the problem, but perhaps worth a check before spending too much time digging into the code.
