/usr/bin/v2ray -c /var/etc/v2ray/v2ray.main.json
or just
/usr/bin/v2ray --version

shows huge VSSZ memory usage, and also cause router to stop response.

And this should be fixed after Go 1.17.2: https://github.com/golang/go/commit/05e6d28849293266028c0bc9e9b0f8d0da38a2e2

4.43.0-2 is already built with golang 1.17.2

See the version of OpenWrt golang package: https://github.com/openwrt/packages/tree/master/lang/golang

Thanks, yes, it is 1.17.2, and I have compiled all of them from sources, but unfortunately it does not works, still ran into OOM and killed :(

[wheelcomplex]

Just for some one who may need: do not use geoip tag (eg,. geoip:cn) in config will avoid v2ray to load geoip.dat which cause the huge memory usage during startup (and trigger OOM killer).

@kuoruan looks like this is not a issue about Go 1.17.2 but something about geoip.data parsing/loading.

I have the same issue as u. I tried setting variable to fix it, but it just worked at the beginning. Now it turned worse.
