That sounds like a DOS attack, to be honest. I usually see weeks pass without a single connection from an actual SPV client, though there are bunch of shitty spy things that pretend to be them. It absolutely shouldn't be making remotely that kind of difference.

uh, also, 125 is the maximum connections.

The only issue it exposes you to are DOS attacks and any bugs in that functionality... though bugs seem fairly unlikely at that point. The DOS attack issues have been exploited in the wild, so for a rarely used and not very useful functionality.

I had upped the max with -maxconnections=500 a while back. All I can say is I have the upload bandwidth to deal with it and it was managed via myfirewall as low priority so any other traffic would supersede it and choke it off. So I guess I never noticed how much it was using on a constant basis, only every time I looked it was 120+ connections inbound and serving 10's of gb/day.

I cut off mainchain, it's now at 61 inbound after 1.5days in that mode and has served 24GB in that time. Slightly down but seems to be going up over time.
DoS attacks suck. But does seem like it's rather pointless in this context. I dunno, I leave it off for now. Sounds like SPV clients are on the way out anyway in favor of other lite methods, might as well show them the door. It's not Gov't, it's just my vote with my node.
