Enabling floodfill cause errors #2099

Closed xxkfqz closed 1 month ago

I spent a long time trying to figure out why, with the firewall disabled and ports forwarded, it constantly displays Network status: Firewalled or Network status: Firewalled - Symmetric NAT. It turned out that if you enable floodfill = true in the config, there will be errors:

root@raspberry:~ # uname -a

5535, 4098>]']

With floodfill = false everything is fine, no errors. I2PD was built from source (from ae267581707db1f51096dac2e393b4e44497492f)

Figured it out myself:

root@raspberry:~ # sysctl kern.ipc.maxsockbuf=6553500
kern.ipc.maxsockbuf: 2097152 -> 6553500

After that everything worked fine
