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:
