Hi,

Varnish itself doesn't dump the core, your OS does it. Most probably, you
want to look at this page:
https://www.freedesktop.org/software/systemd/man/systemd-coredump.html

Cheers,

Hi,

Please keep the mailing-list cc'd.

I would turn it off, the panic message generally is enough and the whole
core isn't that useful.

You can't disable panics, so just disable coredumps

This?

varnishadm param.set feature +no_coredump

Or during startup:

varnishd [...] -p feature=+no_coredump

See `man varnishd` for other feature flags.
