Is /usr/local/www/charon.core a core dump file

[netto]

I noticed my pfSense appliance is running very low on disk space for "/".
After looking around I noticed this file:
-rw–-----  1 root  wheel  2151325696 Feb  5 08:47 charon.core
under:
/usr/local/www

file //usr/local/www/charon.core
/usr/local/www/charon.core: ELF 64-bit LSB core file x86-64, version 1 (FreeBSD), FreeBSD-style, from 'charon'

I am not sure if this is a core dump file or not, but it seems very large file.
I checked on two other pfSense appliances and I did not find the file on the systems.
Is it safe to remove it from system?

Any suggestions

Yeah, this one can safely be deleted unless you intend to debug why's it crashing.
