Thanks for your report.

Can you tell more about your operating environment? What is your
Radiator version, does it have patches, what is your operating system,
is it 64bit or 32bit, what is the load level when you see restarts, is
the memory usage starting to reach system limits etc.

If you are running Linux, does dmesg command show anything special e.g.,
out of memory messages? Do system logs show anything peculiar from the
time the crash happens?

If you already have Trace 4 enabled and there is nothing in logs, it is
hard to say. As I wrote above, can you tell e.g., if you are not running
out of memory when the process dies.

Currently there is no such method. If you take a look at Radius/Log.pm
and sub main::log function, you could add this

$s = "PID:$$ $s";

just before the comment "Catch recursion".

After that all log messages will contain the process ID.
