Seemingly successful install of Exchange 2013 SP1 turns into many errors in event logs after upgrade to CU7

Question

I have a new Exchange 2013 server with plans to migrate from my current Exchange 2007 Server. 
I installed Exchange 2013 SP1 and the only errors I saw in the event log seemed to be long standing known issues that did not indicate an actual problem (based on what I read online). 
I updated to CU7 and now lots of errors have appeared (although the old ones seem to have been fixed so I have that going for me). 
Currently the Exchange 2013 server is not in use and clients are still hitting the 2007 server.
Issue 1)
After each reboot I get a Kernel-EventTracing 2 error.  I cannot find anything on this on the internet so I have no idea what it is.
Session "FastDocTracingSession" failed to start with the following error: 0xC0000035
I did read other accounts of this error with a different name in the quotes but still can’t tell what this is or where it is coming from.
Issue 2)
I am still getting 5 MSExchange Common 106 errors even after reregistering all of the perf counters per this page:
https://support.microsoft.com/kb/2870416?wa=wsignin1.0
One of the perf counters fails to register using the script from the link above.
66 C:\Program Files\Microsoft\Exchange Server\V15\Setup\Perf\InfoWorkerMultiMailboxSearchPerformanceCounters.xml
New-PerfCounters : The performance counter definition file is invalid.

But that one seems unrelated to the ones that still throw errors. 
Three of the remaining five errors are (the forum is removing my spacing between the error text so it looks like a wall of text - sorry):

Issue 3)
I appear to have some issues related to the healthmailboxes. 
I get MSExchangeTransport 1025 errors for multiple healthmailboxes.
SMTP rejected a (P1) mail from 'HealthMailbox23b10b91745648819139ee691dc97eb6@<my domain>.local' with 'Client Proxy <my server>' connector and the user authenticated as 'HealthMailbox23b10b91745648819139ee691dc97eb6'. The Active Directory
lookup for the sender address returned validation errors. Microsoft.Exchange.Data.ProviderError
I reran setup /prepareAD to try and remedy this but I am still getting some.
Issue 4)
I am getting an MSExchange RBAC 74 error. 
(Process w3wp.exe, PID 984) Connection leak detected for key <my domain>.local/Admins/Administrator in Microsoft.Exchange.Configuration.Authorization.WSManBudgetManager class. Leaked Value 1.
Issue 5)
I am getting MSExchange Assistants 9042 warnings on both databases.
Service MSExchangeMailboxAssistants. Probe Time Based Assistant for database Database02 (c83dbd91-7cc4-4412-912e-1b87ca6eb0ab) is exiting a work cycle. No mailboxes were successfully processed. 2 mailboxes were skipped due to errors. 0 mailboxes were
skipped due to failure to open a store session. 0 mailboxes were retried. There are 0 mailboxes in this database remaining to be processed.
Some research suggested this may be related to deleted mailboxes however I have never had any actual user mailboxes on this server. 
If they are healthmailboxes or arbitration mailboxes that might make sense but I am unsure of what to do on this.
Issue 6)
At boot I am getting an MSExchange ActiveSync warning 1033
The setting SupportedIPMTypes in the Web.Config file was missing. 
Using default value of System.Collections.Generic.List`1[System.String].
I don't know why but this forum is removing some of my spacing that would make parts of this easier to read.

Answer 1

Hi Eric
Yes I have uninstalled and reinstalled Exchange 2013 CU7 for the 3^rd time. 
I realize you said one issue per forum thread but since I already started this thread with many issues I will at least post what I have discovered on them in case someone finds their way here from a web search.
I have an existing Exchange 2007 server in the environment so I am unable to create email address policies that are defined by “recipient container”. 
If I try and do so I get “You can't specify the recipient container because legacy servers are detected.”
 So I cannot create a normal email address policy and restrict it to an OU without resorting to some fancy filtering. 
Instead what I have done is use PS to modify extensionAttribute1 (otherwise known as Custom Attribute 1 to exchange) for all of my users. 
I then applied an address policy to them and gave it the highest priority. 
Then I set a default email address policy for the entire organization. 
After reinstalling Exchange all of my system mailboxes were created with the internal domain name. 
So issue number 3 above has not come up. 
For issue number one above I have created a new thread:
https://social.technet.microsoft.com/Forums/office/en-US/7eb12b89-ae9b-46b2-bd34-e50cd52a4c15/microsoftwindowskerneleventtracing-error-2-happens-twice-at-boot-ex2013cu7?forum=exchangesvrdeploy
For issue number four I have posted to this existing thread where there is so far no resolution:
https://social.technet.microsoft.com/Forums/exchange/en-US/2343730c-7303-4067-ae1a-b106cffc3583/exchange-error-id-74-connection-leak-detected-for-key?forum=exchangesvradmin
Issue number Five I have managed to recreate and get rid of in more than one way. 
If I create a new database in ECP and set the database and log paths where I want, then this error will appear. 
If I create the database in the default location and then use EMS to move it and set the log path, then the error will not appear. 
The error will also appear (along with other errors) if I delete the health mailboxes and let them get recreated by restarting the server or the Health Manager service. 
If I then go and set the retention period for deleted mailboxes to 0 days and wait a little while, these will all go away. 
So my off hand guess is that these are caused by orphaned system mailboxes.
For issue number six I have posted to this existing thread where there is so far no resolution:
https://social.technet.microsoft.com/Forums/exchange/en-US/dff62411-fad8-4d0c-9bdb-037374644845/event-1033-msexchangeactivesync-warning?forum=exchangesvrmobility
So for the remainder of this thread we can try and tackle issue number two which is the perf counters. 
The exact same 5 perf counter were coming up and this had been true each time I have uninstalled and reinstalled Exchange 2013CU7. 
Actually to be more accurate a LOT of perf counter errors come up after the initial install, but reloading the perf counters using the script I posted above reduces it to the same five. 
Using all of your suggestions so far has not removed these 5 remaining errors either.  Since there is no discernible impact other than these errors at boot I am not seriously bothered by them but as will all event log errors, I would prefer
to make them go away if possible.
