Released: November 2021 Exchange Server Security Updates

I have 3 node exchange 2019 DAG,

After Installing the security patch I am getting event ID 8019 occasionally.

Here is what it is look like:

Creating extra connection for idle queue: 7 with queue type: SmtpDeliveryToMailbox and next hop domain: mdb02-dag01. Current number of connections is: 1

And also some times email from a server to another server gets delayed by 2 minutes, up on look up, I found that the email gets stuck in email Q for 2 minutes on the originating server and it gets sent to the destination server after 2 minutes.

Here is a what it is look like when an email gets stuck.

PS C:\Windows\system32> get-queue -Server ex01

Identity DeliveryType Status MessageCount Velocity RiskLevel OutboundIPPool NextHopDomain
-------- ------------ ------ ------------ -------- --------- -------------- -------------
ex01\7 SmtpDeliveryToMailbox Active 1 0 Normal 0 mdb02-dag01
ex01\Submission Undefined Ready 0 0 Normal 0 Submission

Anyone else experiencing this?
