Hello fail2ban users,

I am getting the following in the logwatch email today. This is the first time I'm getting this in the logwatch email. I got 364 "drop open request" lines, but I'm showing a sample below.

I don't know what this means. Is this a DDos attack ? I have checked the iptables and fail2ban didn't ban that IP under any jail.

Please help. Thanks.
