[BUG] Closing open session in favor of incoming prekey bundle / Closing session: SessionEntry

[Oscar Guindzberg]

Describe the bug
I have a server with 15 connected whatsapp users.
I find this on the log from time to time:

Closing open session in favor of incoming prekey bundle
Closing session: SessionEntry {
  _chains: {
    'xxx': { chainKey: [Object], chainType: 2, messageKeys: {} },
    'xxx': { chainKey: [Object], chainType: 1, messageKeys: {} }
  },
  registrationId: 2031812068,
  currentRatchet: {
    ephemeralKeyPair: {
      pubKey: <Buffer xx xx xx ...>,
      privKey: <Buffer xx xx xx ...>
    },
    lastRemoteEphemeralKey: <Buffer xx xx xx ...>,
    previousCounter: 0,
    rootKey: <Buffer xx xx xx ...>
  },
  indexInfo: {
    baseKey: <Buffer xx xx xx ...>,
    baseKeyType: 2,
    closed: -1,
    used: 1718654391536,
    created: 1718654391536,
    remoteIdentityKey: <Buffer xx xx xx ...>
  }
}

I know this is printed by libsignal, I guess these lines are the culprits:

• https://github.com/adiwajshing/libsignal-node/blob/11dbd962ea108187c79a7c46fe4d6f790e23da97/src/session_builder.js#L74

• What do your connectOptions look like?

const { version, isLatest } = await fetchLatestBaileysVersion()
const { state, saveCreds } = await useMultiFileAuthState('myPath')
const msgRetryCounterCache = new NodeCache()

        async function getMessage(key)  {
            if(store) {
                const msg = await store.loadMessage(key.remoteJid, key.id)
                return msg?.message || undefined
            }
            // only if store is present
            return proto.Message.fromObject({})
        }

 makeWASocket({
            version,
            logger,
            printQRInTerminal: false,
            mobile: false,
            auth: {
                creds: state.creds,
                keys: makeCacheableSignalKeyStore(state.keys, logger),
            },
            msgRetryCounterCache,
            generateHighQualityLinkPreview: true,
            // ignore broadcast and newsletter messages
            shouldIgnoreJid: jid => !jid || isJidBroadcast(jid) || isJidNewsletter(jid),
            // implement to handle retries & poll updates
            getMessage,
            shouldSyncHistoryMessage: () => true,
