No expert here but in my sapphire directory I've got more than a dozen core.xxxx files - mostly over 80mb each.

Can I delete them all?

They are all recent - last few days - only issue that's been reported is memory exhausted on using search.

Any help would be much appreciated.

err, really? do you have a module installed that could be creating these? there is nothing in the default installation that I know of that would create these and if I saw them i would be thinking i had been hacked.

Hi Hamish,

Can you help me understand what these files are - they seem to only have been created in the last few days - so that I can troubleshoot.

It would be ideal to be able to delete them, they are taking up a gig of disk space. Can you or anyone else confirm deleting all is OK?

Core dumps are generated by PHP itself sometimes when it crashes - its just a memory dump. Unless you're planning to use them for debugging it's fine to delete them.

That's helpful ajshort. Thx.

What is it that's being dumped? The files are 80MB+.

I've checked error logs and there's nothing there for that period except a few 'memory exhausted' errors in relation to sapphire/core/Object.php - which seem to have been fixed by up'ing memory limit using php.ini method.

Appreciate any help to avoid this happening again.

I'm having this problem too - I upgraded a site to 2.4 and noticed the site was running out of allocated disk space a lot. These core.**** files are the culprit.

Any pointers welcome - based on other similar threads I'm assuming it may be a PHP bug in the core of a particular PHP version?
