Hi, Recently, I decided to use PHP FPM, installation went well, I configured it with Nginx. I can run php script without any issue. But when I used a script to connect to Oracle database using oci module, I got a blank page. Below is the code I am using in script. <?php $c = oci_connect("mydb", "password", 'DEV'); if(!c) { $e = oci_error(); print htmlentities($e['message']); exit; } else { echo '<br />Connection is OK'; } ?> If I run this script from command line it works well. ------- /usr/local/php/bin/php db_test.php Connection is ok ------ But when I run it from Web it does not return any thing, I got following error in FPM log, nothing else. WARNING: [pool www] child 15712 exited on signal 11 (SIGSEGV) after 3986.160925 seconds from start It is getting segfault. Anyone can suggest what could be possible reason. PHP veriosn 5.3.8
