[pmwiki-users] Have found files named : core.XXX

[ABClf]

Hello,

Checking my website on ftp, I discovered a few unexpected files named :
core.17422
core.19723
etc.
(5 files as of now).

File size is quite big : around 18 mo each ; they look like binary
files (selecting a file, when I click on edit, then I get a liste of
numbers like that – 0000 0000 4000 3800 4401 0000 0000 0000 – instead
of text).

Does anyone have any idea where these files come from ?
Does pmwiki creates such kind of core.XXX files ?

Thank you !
Gilles.
