I am now experiencing the same error on multiple vms across multiple
chassis.
4.97.1
on FreeBSD 14.0p5
It is unclear to me how to find a newer version such as a testing version?
Is there a 4.97.2 forthcoming any time soon ? even a beta ?

I created a new VM for exim . I've loaded many VMs .. this chassis has
several active VMs actually. vmWare.
I have never seen the following .. it seems like a chassis memory
error .. however the other two active VMs on this chassis run without
issue. So I wonder ..
is there anything on exim that could -possibly- be triggering this ?
SSL ? (this is on FreeBSD 14.0)
these errors show up in the exim panic log. stopping the exim instance
and restarting it, gets it up and running, but eventually it happens
again.
Which version of Exim ?
What is in the error log at that time ?
Recent crash bugs include:
https://bugs.exim.org/show_bug.cgi?id=3059
SIGSEGV on SMTP delivery if remote badly responds
while PIPELINING and CHUNKED is active
https://bugs.exim.org/show_bug.cgi?id=3047
doesn't crash on known systems, but attempts to use a bad address
(though nearer -2G than -100).
What version of PCRE2 are you using?
Are you up to building a patched version of Exim -
both of these have patches which may help *if* you have that problem ?

I deleted the vm, reloaded it, and eventually the same issue resurfaced:
