As the title suggests, thanks.

Hi author,

It seems that we should set an upper bound for the score of vertices in lukes_partitioning.py, or the score of a single node may exceed the max_size in lukes_partitioning() and result in a NoneType Error in python.

Hi there,

I use the command line in README to set up the environment and fuzz libpng. However, after running for 1 hour it switches to horse-fuzz. When I use ps -ef to look at the horse-fuzz processes, it shows they are defunct. Then I look at the task directory in the active_run folder, and I found the task directory is empty.

I wonder if is this a correct situation, or something goes wrong.

I'm looking forward to your reply.
Thanks

Hi @thuanpv,

I am tyring aflteam by replacing afl with aflpp (others are not changed). After running aflteam-manager.py, I only see the output screen of aflpp. I wonder how I can keep track of the overall status of the whole fuzzing process. Any help will be appreciated. Thanks!

Hi author, I wonder why you disable the optimization classify_counts() in horsefuzz. Could you please provide an example with more details? It seems that the the function has_new_bits() will also be misled to some extent.
Thank you for replying!

Hi there,
I tried to fuzz tcpdump with aflteam. After running a while, aflteam-manager.py got crashed but the master AFL process still run. I would like to know how to fix this issue. Please see following backtrace.
