Integration tests with p2p connectivity often hang

[DieMyst]

We have integration tests in aqua that go through 3-4 nodes. And it often hangs. If it hangs once, it will hang some long time later. I often use a bad option to avoid this - changing environment in tests. This is repeated in different networks and on different nodes. Something from the logs could not be understood. Aqua code:

func viaArr(node_id: string, viaAr: []string) -> Info:
    on node_id via viaAr:
        p <- Peer.identify()
    <- p

in viaAr were constantly used these nodes as arguments: relays[4].peerId, [relays[2].peerId, relays[1].peerId]. For krasnodar:
