Please give proof that the log file still is open, which exim process
has it opened, and what the exim process is doing while keeping the
log file open.

I have never seen this issue on any of my systems.

This is not an acceptable fix as it disrupts exim operation and will
not help since I suspect that the log file is not kept open by the
smtp listener process. All other exim processes are "short lived".

But it happens.
