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 ?
