Mailing List Archive: memory issue

I created a new VM for exim . I've loaded many VMs .. this chassis has
several active VMs actually.
I have never seen the following .. it seems like a chassis memory error
.. however the other two VMs on this chassis run without issue. So I
wonder ..
is there anything on exim that could -possibly- be triggering this ?
SSL ? (this is FreeBSD 14.0)

Merry Christmas to all.

Obviously yes. But we can't guess what. At least it's consistent;
deref of a value "-4". What we really need is a stacktrace.
Were it a current Exim version I'd expect to see one, on FreeBSD.
What are you running?

Alternatively, can you set up for getting coredumps from setuid programs?
