Have you tried reproducing the issue with the latest release?
Yes, this is the latest release (to my knowledge) and this issue has persisted across versions
Steps to reproduce the issue (paste the query/schema if possible)
We have a relatively large GraphQL schema. When trying to apply it to an empty Dgraph instance, the process times out and the container dies with lots of errors, finishing with the following:
goroutine 134229 [semacquire]:

W0209 06:28:01.303786 43 pool.go:267] Connection lost with localhost:7080. Error: rpc error: code = Unavailable desc = transport is closing
Expected behaviour and actual result.
Expect the process to take less than a few minutes, but it times out and dies.
NB: due to privacy issues, I cannot post the schema publicly here, so I may need to email it to someone at Dgraph.
