Error panic: sync: WaitGroup is reused before previous Wait has returned

[fabioaraujopt]

We have cloudflare-exporter running with several restarts due to this error:

/app/main.go:129 +0x278

main.fetchMetrics()
usr/local/go/src/sync/waitgroup.go:141 +0xb8
sync.(*WaitGroup).Wait(0x400010c070)
goroutine 2972 [running]:
panic: sync: WaitGroup is reused before previous Wait has returned

Any thoughs on that?

Thank you
