<p>I've been trying to get useful information (the full stack) from Cowboy error reports. But all of our reports are truncated. I found this

http://stackoverflow.com/questions/17596686/truncated-error-report-in-erlang</a>, but the solution didn't work for me.<br>
</p>
<p><br>
</p>
<p>I looked at the emulator source code and found the undocumented +# switch which controls precision. Using this switch, I verified that the errors are being truncated by the emulator itself (see below).<br>
</p>
<p><br>
</p>
<p>Is this truncation intentional or a bug? Is there a better way around it than the +# switch?<br>
</p>

<p>At a higher level, is there a better way to get error/crash information from a process than going through error_logger? We're using lager and erlbrake and both add error_logger handlers that parse the text error reports. I would much rather deal with the
reason term directly. Is there a way to be notified of process termination other than error_logger?<br>
