> Repeat Out Times traversal hangs indefinitely on first execution
> ----------------------------------------------------------------
>
> Key: TINKERPOP-2767
> URL: https://issues.apache.org/jira/browse/TINKERPOP-2767
> Project: TinkerPop
> Issue Type: Bug
> Components: server
> Affects Versions: 3.5.3
> Environment: Windows 10
> Reporter: Simon Zhao
> Priority: Major
>
> Originally encountered when fixing TINKERPOP-2754
>
> The following traversal in JS seems to cause hanging the first time you run
> it on a newly launched gremlin-server (3.5.3) via docker
>
> {{await g.V('1').repeat(_.out()).times(1500).next();}}
>
> The same hanging occurs in gremlin-go.
>
> {code:java}
> _, err = g.With("evaluationTimeout",
> 1000).V("1").Repeat(gremlingo.T__.Out()).Times(int32(1500)).Next() {code}
>
> The timeout is optional, but indicates that something is going wrong since it
> is not returning. Interestingly enough, if the timeout is very low, then it
> won't hang because it will say the timeout was exceeded. This indicates that
> if the traversal is completed within the timeout, it's just not returning for
> some reason on the first call.
>
> If you were to write a script and invoke this snippet of code, it will hang.
> If you forcefully terminate the script and rerun it, then it doesn't hang.
>
> main.go
> {code:java}
> package main
> import (
> gremlingo "github.com/apache/tinkerpop/gremlin-go/v3/driver"
> "log"
> )
> func main() {
> driver, err :=
> gremlingo.NewDriverRemoteConnection("ws://localhost:45940/gremlin")
> if err != nil {
> log.Print("Err creating DRC")
> return
> }
> defer driver.Close()
> log.Println("Start")
> g := gremlingo.Traversal_().WithRemote(driver)
> LABEL := "test"
> _, err = g.V().HasLabel(LABEL).Drop().Next()
> _, err = g.AddV(LABEL).Property(gremlingo.T.Id, "1").Next()
> _, err = g.AddV(LABEL).Property(gremlingo.T.Id, "2").Next()
> _, err =

> "e1").Next()
> _, err =
> g.AddE(LABEL).From(gremlingo.T__.V("2")).To(gremlingo.T__.V("1")).Property(gremlingo.T.Id,
> "e2").Next()
> if err != nil {
> log.Println("Error during setup")
> return
> }
> log.Println("Start the problematic traversal")
> _, err = g.With("evaluationTimeout",
> 1000).V("1").Repeat(gremlingo.T__.Out()).Times(int32(1500)).Next()
> if err != nil {
> log.Println("Error with the problematic traversal, but we didn't hang")
> return
> }
> log.Println("End")
> } {code}
