I have a website that is running on shared linux web hosting with Joomla as CMS. Some core.<6-7 digit number> files are automatically being created. Each file is about 20-30 MB in size taking a lot of space. I have deleted these files for now but they again appear Anyone plz help me what to do??
It depends on what is creating these files. If they're core dumps it means your server is crashing, although it would be unusual to see core dump files in the web space for shared hosting. What is in the files? Can you post an example of a specific, complete file name? When and how often are they being created?
Exact file names are: core.63762 - 21 MB core.793319 - 24 MB I dont know what these file contain. Around 5 to 10 such files are being created daily.
Sounds like core dump files but no way to be sure without examining them. Core dumps are created when certain applications "misbehave" and Linux terminates the application, assuming Linux is set to produce a core dump file. In extreme cases the misbehaving app can crash your server so you should investigate what is causing the core dumps. Usually, your host will intervene when you're on shared hosting and this happens frequently. I would contact your host's technical support and ask them to look into this. They're much better equipped to figure out what is happening. Are you doing any heavy-duty graphics processing in your Joomla? Also be sure that Joomla and all of your plugins are up to date.
