So I don’t have a problem with memory consumption – as far as I’m concerned it’s there to be used. I was having the same failure before the 8G dimm crapped out, so I was seeing this on a 16G machine. In any event, it’s Win7 not Linux so I don’t have the “free” command available. However the numbers from the task manager before starting are:
8065 total
1955 Cached
4952 Available
3018 Free
I did shut down the “memory pigs” but that’s relative as nothing was really consuming much beyond a couple of hundred meg.
As I ran restic/check I watched the total memory in use and it didn’t rise above 6.5G before restic threw the out of memory exception. GOGC=20 didn’t seem to have any effect.
