Magento

I am seeing 3 core.<numbers> files in my magento root folder with each being a little over 50mb.

One example of this file is core.4542

Why are these files in the root magento folder?

If you are still looking for an answer:

I just had these files as well, this morning, and after a quick google-search I have the imporession that these files are allmost certainly not connected with magento but caused by a crashing script and usually contain memory dumps. You should be fine deleting them. If they appear again it probably means you have a problem with your server (possibly but not neccessaryly a hardware-problem)

I spoke to a member of my web host tech support team and and he confirmed what you have said nanos.

Thanks.
