If you are a VPS or Dedicated customer with command line (shell) access, most of the information in the core dump can be found by running either one of these two commands:<\/p>\n<p>gdb -c core.####<\/p>\n<p>strings core.####<\/p>\n<h2>Reviewing Core Dump Files on Shared Servers<\/h2>\n<p>If you are on a shared hosting package, for security reasons you do not have access to the command line. For our shared customers, we\u2019ve created a basic PHP script that uses the commands above to allow you to find any core dump files in your account. The script can be found here:<\/p>\n<p class=\"alert alert-warning\"><a href=\"\/support\/files\/scripts\/coredumpcheck.txt\">https:\/\/www.inmotionhosting.com\/support\/files\/scripts\/coredumpcheck.txt<\/a><\/p>\n<p><b>Please note!<\/b> For security reasons, please either delete this file after using it <em>OR<\/em> <a href=\"\/support\/website\/password-single-file-htaccess\/\">password protect it<\/a>.<\/p>\n<ol class=\"article_list\">\n<li>Upload the coredumpcheck.txt file to the folder where you want to view core dumps.<\/li>\n<li>Rename the file to coredumpcheck.php<\/li>\n<li>Access coredumpcheck.php file in your browser. For example, if you have core dumps in your public_html folder then you would go to https:\/\/example.com\/coredumpcheck.php<\/li>\n<li>The script will list all the core dumps in the current directory. Click any of the file names to view more details about the core dump.\u00c2\u00a0<\/li>\n<li>Look under the \u201cRUNNING: gdb -c core.30387\u201d heading to find the script that is causing the problem.
