Memory is slowly increasing until OOM

[lrfdehao]

I wonder why my vm.Run() is causing the program's memory to grow slowly.

Showing nodes accounting for 233MB, 83.09% of 280.42MB total
Dropped 268 nodes (cum <= 1.40MB)
Showing top 10 nodes out of 200
      flat  flat%   sum%        cum   cum%
  142.73MB 50.90% 50.90%   142.73MB 50.90%  github.com/robertkrimen/otto/parser.ParseFileWithSourceMap

can i release the Value{} object memory by myself?

Can you provide a code example showing the issue?

func a() []struct {
        var res []struct
        vm := otto.New()
        _, err = vm.Run(src) // src: js script , too long
        if err != nil {
                return nil, err
        }
    if value, err := vm.Get("prefix"); err == nil {
                for _, v := range value.Object().Keys() {
                        data, _ := data.Export()
                        if data, ok := data.([]map[string]interface{}); ok {
                                for _, y := range data {
                                        // res append
                                        // some logic append []struct
                                }
                                return &res
                        }
                }
        }
}

// src: js script , too long

The problem is likely in here - could you try cutting the javascript down to something minimal to demonstrate the issue? You could even start off with an empty script perhaps, to prove the issue isn't in the rest of the code.

All right, thank you. I'll do a double check here
