core.XXXXX, what's that?

[hichew]

can i delete that files? (image attached)
they took close to 2 gig of space

and what's the core.[number] mean?

Those probably are the result of crashed PHP processes. You can remove those files.

it's getting worse now...
i had over 3000 core.xxxxx files (each 7mb) and everytime i delete the files.. others are popping...
any idea?
how to fix this?

You can exam the core file by following command,

gdb <lsphp_path> <core.xxxx>
bt

It can tell you the approximate location where PHP crashes. You can file a bug report to the PHP group. Also check lsws/logs/stderr.log and lsws/logs/error.log for PHP related errors.

Maybe upgrade the php binary to the latest.
