Massive Memory Usage

[grigzy28]

After a bit the siad.exe gives the following error and is also taking up 3+ gb of ram and is also making the sia-ui unresponsive and the whole PC comes to a crawl

I experienced similar behavior on Linux, while uploading 3 moderately large files (300 MB - 1 GB) at the same time. My guess is that siad is either not releasing memory after uploading some blocks, or duplicating many many blocks and uploading them in parallel (thus filling system memory). In the latter case, some limitation on RAM usage should be imposed, rather than assuming "infinite" memory.

Well, I wasn't uploading any files. I experienced it in the windows UI.

What I think happened was that siad was still syncing the blockchain while I tried to unlock the wallet in the windows UI. Thus causing the problem with the consensus. When I used the siac command line client to unlock the wallet it worked fine.

Same problem observed in linux with siad when uploading folder of random files with siac renter upload. 4GB memory was not enough for siad, had to enable swap to make it run. It simply uses too much ram.

Hello I have the same problem after uploading 15Go, Sia-UI take 10 Go in RAM

I used Sia with duplicati and duplicati become slower and slower after each upload

any news on this topic ?
