"too many open files" #3

Closed vielmetti closed 2 years ago

vielmetti commented 2 years ago

I see one post to alt.social, but soon afterwards the system crashes with

ERROR┐╔═blockstore══════go-ipfs-blockstore@v0.1.6/blockstore.go:218═════blockstore.AllKeysChan got err: walk failed: open /Users/emv/.ipfs-sh84/blocks: too many open files

What does your ulimit -n say while you're running it? Was it increased to > 1024? If not, you can try to manually do so , e.g. ulimit -n 2048.

With ulimit changed, no errors.

Will check if I can set ulimit on start.

@vielmetti please try setting your IPFS repository to lowpower profile and test with that:

ipfs config profile apply lowpower

See this for more info.

I've tested the above profile on the macbook, as well as two small-scale VPS and they've all been running for the past day with no issues at all. This seems to have more or less fixed this issue. I've documented it already in the README, so people should be go to go.
