Does anyone have a good recommendation for per-OSD memory for EC? My EC test blew up in my face when my OSDs suddenly spiked to 10+ GB per OSD process as soon as any reconstruction was needed. Which (of course) caused OSDs to OOM, which meant more reconstruction, which fairly immediately led to a dead cluster. This was with Giant. Is this typical?
