two days ago I tried to open a dual-funded channel and yesterday my
C-Lightning node started crashing.
Have a look at https://github.com/jsarenik/clightning-dual-crash-logs as I
think it may be related to the DoS you mention.
If it is related, let me know and I can provide all the details.
Best regards to all!
