Bug #15940: Segmentation fault (11)

From: uwe.kolsch@wax.co.uk Operating system: Linux PHP version: 4.1.2 PHP Bug Type: Apache related Bug description: Segmentation fault (11) There seems to be a bug in PHP 4.1.2. Being not an expert in this kind of stuff I can only report the symptoms. We are running the site for quite a time without any problems (4.0.6 compiled with configure --with-apache=../apache_1.3.23 --enable-track-vars --with-interbase=/opt/interbase --enable-trans-id). After upgrading to 4.1.2 the output of PHP did occasionally - not always - create only parts of the expected output. The apache error log showed "child pid 8354 exit signal Segmentation fault (11)" for about every 20 sec. The site has quite a high load with about 80 kByte/s at the time of watching this. Switching back to 4.0.6 made the problem disappear. On a other server with almost exactly the same config the problem does not occur. The only difference between the two is that the load is lower (between 1 and 4 kBytes/s) and that Interbase is not used by any PHP script on the server but support is compiled in and interbase is running. -- Edit bug report at http://bugs.php.net/?id=15940&edit=1 -- Fixed in CVS: http://bugs.php.net/fix.php?id=15940&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=15940&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=15940&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=15940&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=15940&r=support Expected behavior: http://bugs.php.net/fix.php?id=15940&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=15940&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=15940&r=submittedtwice
