POTracking down a segmentation fault 11 to large PHP code base
text
Body
copied!<p>Ok so have a fairly huge in house system. We have a nice friendly host who generally work with us keeping things working if something ever goes wrong, or at least points us in the right direction.</p> <p>A while ago we had to take a copy of the code and host it on a clients external dedicated server, hosted with Rackspace. Considering everything was working fine for a number of months, all of a sudden the server kept throwing hissy-fits and segmentation faults eg</p> <blockquote> <p>[notice] child pid 8628 exit signal Segmentation fault (11)</p> </blockquote> <p>Even though no code had been changed, the hosts have said its probably a PHP issue and the devs (us) would have to look into it. I haven't even seen a problem, just that at certain times when the apache logs rotate (late at night) this is causing it to fall over.</p> <p>I got them to enable core dumps, and I am armed with a bunch of them, and <a href="http://www.omh.cc/blog/2008/mar/6/fixing-apache-segmentation-faults-caused-php/" rel="noreferrer">Fixing Apache Segmentation Faults Caused by PHP</a>, but rackspace seem to have moved all the php and apache source dirs to god knows where, I cant find .gdbinit anywhere on the server using 'find', and about all I can get out of gdb is</p> <pre><code>Program terminated with signal 11, Segmentation fault. #0 0x00002b8d6fc36c60 in ?? () </code></pre> <p>...which couldnt be less helpful if it tried!!!</p> <p>Any ideas on where to start with tracking down this supposed problem in my code?</p>
