FBSD 14.0 / exim 4,97.1 - exim SIGSEGV

I upgraded both of the captioned versions at the same time, so it is not 
clear to me which is causing this issue.. however, since upgrading, 
often but without any discernible cycle or frequency, exim refuses 
incoming connections, and logs the following:

2024-05-19 07:21:00 SIGSEGV (fault address: 0xffffffffffffff70)
2024-05-19 07:21:00 SIGSEGV (maybe attempt to write to immutable memory)
2024-05-19 07:21:00 SIGSEGV (44427 handling incoming connection from 
[127.0.0.1])
2024-05-19 07:21:00 SIGSEGV (fault address: 0xffffffffffffff70)
2024-05-19 07:21:00 SIGSEGV (maybe attempt to write to immutable memory)
2024-05-19 07:21:00 SIGSEGV (44432 handling incoming connection from 
[127.0.0.1])
2024-05-19 07:21:00 SIGSEGV (fault address: 0xffffffffffffff70)
2024-05-19 07:21:00 SIGSEGV (maybe attempt to write to immutable memory)
2024-05-19 07:21:00 SIGSEGV (44433 handling incoming connection from 
[127.0.0.1])

To get exim working again, I shutdown the service and restart it, and it 
works again as expected.

This happens across multiple chassis, both VMs and bare metal, so the 
root cause is not system memory.

I am trying to establish a troubleshooting route, and wondering if 
others are experiencing this as well?
