[dancer-users] Dancer crashing

[Hermann Calabria]

I have a large Dancer application that crashes rarely with the attached stack trace. I haven’t yet identified any specific code or pattern that triggers the crash; if I restart (perl ./bin/app.pl) and repeat exactly what I was doing prior to the crash, it usually works just fine.  Versions:
Perl 5.26.2
Dancer 1.3500

Is this a known problem?  Solutions?

Stack trace:
