@Taek well I'm glad it's not 4GB! I haven't uploaded any files. Only hosting. When the disk is idle (5-10% usage) Sia still uses about 25% of CPU. Not sure if this has any relevance, but there's about 233 GB of storage that's been used. I've also been running Storj to see how it compares and it does seem to be less CPU/RAM hungry than Sia. Although it's only using about 170GB of storage. So this might explain why. I can live with this issue for the time being, but not indefinitely! Let me know if there's any other info I can provide that will help. Good luck with the improvements!
@Taek: The SIA UI error upon start up.. Seems some files get corrupted. I was however able to recover the contracts and seem to continue to get files in the storage. It is not my own files - it is the files that I host I'm worried about - to loose collatteral on.. It is working now, but it will hap pen again in my setup up I'm sure... I have close to 300 contracts - so far I see no errors... :-) But really look forward to a self restoration feature, to not loose anytihg upon write/error, but again I'm worried on the hosting file side of things..
@alexsavin: the most recent release (v1.1.1, visible in the sidebar) does not have this problem. What you should do is close Sia, download the new version, delete your 'renter/hostdb.json', and then run the new version. After a few minutes you should see the host count start to climb, until it reaches ~70 or so.
@Taek UPDATE! I'm tentatively optimistic that the problem has been cured (for the time being). I deactivated IPv6 in the network settings and it seems to have stopped the auto announcements. It's been about 36 hours without one occurring and I've received a couple of contracts during this time and more storage has been allocated. Deactivating IPv6 doesn't seem to have affected any other programmes, but this may cause a conflict further down the line when IPv6 adoption becomes more commonplace. Feel free to request further logs in future if it will help you counteract this problem. The refund offer is much appreciated. Good to know you're a fair person. I'm sure this is only one less thing in a list of many for you to worry about, but if there's anything we've both learnt it's to keep persevering!
