Troubleshooting

This page describes several of the issues that can be encountered when testing with DeepState.

I'm getting a FileNotFound error regarding fuzzer queues/stats during ensemble fuzzing

This means that one or many of the base fuzzers being used for ensemble-fuzzing threw an internal exception, but the ensembler continued anyway. For fuzzers like AFL and Angora, check to make sure that the core dump pattern is set as so:

$ echo core | sudo tee /proc/sys/kernel/core_pattern

If the internal errors were not thrown to STDOUT by the ensembler, check the output from running each base fuzzer singularly.
