Host wallet mysteriously sending lots of small transactions

[mtlynch]

Hey Sia gang, I'm seeing weird behavior on the wallet of my Sia host node. I'm both mining and hosting on the same wallet. I see my regular transactions coming in for 2,000 and 1,000 from mining on SiaMining. I'm also seeing lots of small transactions leaving my wallet of 1.3 SC, often transactions that show as 0 SC:

Other details:

• I'm hosting, but my storage is 100% full
• I'm not renting at all
• I'm seeing a lot of errors in my host.log about reaching my collateral budget

Posted some more logs that might be relevant: https://gist.github.com/mtlynch/21aeb1fc8fb8f94fca290205008146b7

Any idea what might be happening?

The 0 SC transactions can be ignored, it just means the wallet sent money to itself (usually a refund/'change'). As for the rest... It's hard to say. I would like to add more fine-grained logging to the wallet so that we can see the exact reason for each expenditure.

I also see small outgoing transactions having 100% host:

For your small contracts explorer says "File Contract Revisions", for my it says "Storage Proofs".

I may be having a similar issue I have a lot of .6 txs and I was never paid my last 1000 payout from siamining, The block explorer also says I spent said coins! Posted in reddit about it https://www.reddit.com/r/siacoin/comments/6gxhzi/im_missing_sc_and_what_are_these_6_transactions/

Can confirm I have this one one host as well now. Just started happening about 4 days ago according to wallet activity.

I'm curious if this is caused by the announcer at all? The host this bug is hitting is not set with a static IP. It is static, but is configured to (determine automatically) in the log files. It happens every 4 hours without fail, and in the log file, every 4 hours I get this entry:

• No manually set net address. Scanning to automatically determine address. 2017/06/29 20:41:04.052303 upnp.go:43: No manually set net address. Scanning to automatically determine address.

Seems coincidental?

Will get a DDNS assigned to this in the morning to see if that quiets it down.

Had a weird problem don't know if it's related my last payout of 500 coins says it has been spent.... Even though I have not spent it neither has it been received at bittrex

I am also experiencing this problem where 0 and -0.6SC transactions have been randomly happening while using Sia-UI 1.2.2 on macOS. It may be because I started "accepting contracts"? This seems like a bug to me -- I had no idea I would start to lose/transfer coins.

I met similar problem before. In my case, I created some contracts (by setting the allowance) although I haven't uploaded any files on the Sia network yet. Then every few days, there're some transactions in the Wallet tab implying that my SC are running away. My final solution is cancel all the allowance by:

Click the Terminal tab and enter:

# before executing the following command, please run `renter allowance -h` first to make sure what's going on
renter allowance cancel

After that, I checked with renter allowance and renter contracts to make sure there're no contracts or allowance anymore.

renter allowance

Allowance:
    Amount: 0 H
    Period: 0 blocks

renter contracts

No contracts have been formed.

0 SC Spent / 0 SC Allocated

Same happened to me as a renter without any file uploaded. Using renter allowance cancel seems to fix the issue. However, I lost the SC allocated, it didn't go back to my wallet. Maybe that's the way it works.
