Summary0001813: Receiving UDP flood for several minutes, rev 17144
DescriptionI had the transport process dead, stopped at gdb... and for more than 20 minutes, I had network troubles. When I run 'tcpdump -n', I noticed a udp flood like this:
19:48:39.309513 IP 131.159.74.67.2086 > 192.168.1.34.2086: UDP, length 1400

eating all my download bandwidth, so DNS was not working for me during that time.
Steps To ReproduceI don't know
TagsNo tags attached.

Do you have any idea about the bandwidth at which you received the UDP traffic, and how it relates to the bandwidth you (originally) configured for your GNUnet peer? It could be a bug, but it would help to know if this was anywhere near the bounds of what you had configured...

I have:

[transport-udp]
MAX_BPS = 1000000

[core]
TOTAL_QUOTA_IN = 65536
TOTAL_QUOTA_OUT = 65536

I've 3Mbps (300KB/s) of incoming bandwidth.

Should be fixed in SVN 17748.
