Analyzing Core Dump File

Yeah, I know core dump files may eat up user’s space quickly. But it is definitely a sign that something wrong with their scripts. So, keeping coredump files is sometimes useful so that we can analyze it properly. Here’s how to analyze core dump files :
strings /home/user/public_html/core.11051|head
You will find what scripts causing the coredump files.
or get a clear view with :
gdb /usr/bin/php /home/user/public_html/core.11051

Hope it can be useful for you!

find . -name ‘cache_*’ | xargs rm
