EdgeTransport.exe consume memory on Exchange 2010

Hi all,

I am new to this forum and also new to Exchange.  We are using Exchange 2010 SP1.  It'd been working fine until yesterday.  Here is our summary:
   Exchange 2010 on MS server 2008.
   16 gig memory
   2 TB hard disk
   We still have plenty of hard disk space.
From time to time, it used up all 16gig of memory and lockup the server.  I see EdgeTransport.exe used memory from 2gig to 10 gig.  It will lockup the server for about 1 minute and then everything start to work again.  

I have tried:
   Install SP1 Rollup 4
   Order more memory
   Disable antivirus software.

Is there anything else I can try?

Thanks for all the help.

Exchange 2010 SP1 rollup 4 is very old. I would strongly suggest that you start by updating the server to at least SP2, preferably SP3.

Primary cause of this issue is AV software on the server not having the correct exclusions in place.
Disabling the AV isn't really enough - if you want to rule it out then it must be removed and the server rebooted.

It can also be caused by AV or antispam software that is integrated in to Exchange. As above, if you want to exclude it as being the cause - remove and reboot.

However bringing the server up to date may well help.

Install SP3 directly. Steps are here:

Steps Upgrading Exchange 2010 SP1 or SP2 to SP3:

My Lab Setup: 2 node Multi-role server with DAG.

1) Upgrade the schema for Exchange 2010 SP3. If you have Enterprise and Schema Admin rights, setup will do it automatically, however if not, then AD team is required to perform this task.

Purpose of this Schema Update:

In Order to have the Exchange 2010 SP3 deployed across the environment, it is a prerequisite to have the Active Directory Schema to be extended for supporting Exchange 2010 SP3. During this upgrade, the Active Directory Schema will be extended to support Exchange 2010 SP3.

Steps to be performed for this upgrade:

Reference Article –

Prerequisites: AD account need to be member of following groups
Member of: Domain Admin, Enterprise Admin, Schema Admin

Install Active Directory Management Tools (Run this Command, if Required)
ServerManagerCmd -i RSAT-ADDS

Software Location Exchange 2010 SP3

Download it and extracting it run below command for preparing the schema.

 setup /PrepareLegacyExchangePermissions (Optional):
 Check C:\ExchangeSetupLogs\ExchangeSetup.log for successful completion
 Setup /PrepareSchema
 Check C:\ExchangeSetupLogs\ExchangeSetup.log for successful completion
 Setup /PrepareAD /OrganizationName:"Your Org Name"
 Check C:\ExchangeSetupLogs\ExchangeSetup.log for successful completion

2) Steps for Upgrading Exchange 2010 to SP3

Software Location:
1) Exchange 2010 SP3: http://www.microsoft.com/en-in/download/details.aspx?id=36768

Note: Any Interim Updates for Exchange Server 2010 must be uninstalled prior to installing this update.

As I have all roles in one server in a 2 node DAG. Kindly perform the below steps.

Phase 1: Upgrading Database Availability Groups to Exchange 2010 SP3 (Start with Passive)

Note: Make sure to take full Exchange backup, including system state or any custom setting related to CAS role. Do save the OWA folder under bin path too. During SP3 installation, Exchange setup removes all SP2 related folders; in case you have any proxying it might fail, so make sure to upgrade all servers, however one by one.

1) Open Exchange Management Shell, browse to script folder and run below command
.\StartDagServerMaintenance.ps1 -serverName servername

Note: This script move all Exchange related component including database to another server.
2) Disable the Forefront by using below command (It might ask you to stop few Exchange services)

fscutility /disable

3) Stop the OS Antivirus services and Monitoring Agent for Microsoft Exchange Server

4) Verify Backups are completed.

5) Run the SP3 setup files using GUI or goto run setup /m:upgrade. If you are getting IIS component error goto run setup /mode:upgrade /installwindowscomponents

Note: If you are getting this error "A Restart from a Previous Installation is Pending"

Open regedit and delete the HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\PendingFileRenameOperations key and Rerun Setup.

Ref: http://technet.microsoft.com/en-us/library/cc164360(v=exchg.80).aspx

6) Reboot the server

7) After reboot verify below logs for any error:
Event Logs
Setup Logs (C:\ExchangeSetupLogs)

Services - All Exchange related services are running.
Check IIS Settings are not changed.
Check Authentication settings from EMC for OWA/OMA/ESW. If you find any change revert back to old.
8) Enable Forefront Protection for Exchange. Command fscutility /enable (It might ask you to stop few Exchange services)

9) Start OS Antivirus and Exchange Monitoring Agent Services
10) .\StopDagServerMaintenance.ps1 -serverName servername

11) Now use same steps on another server in DAG.


Phase 2: Upgrade Management Tools

If you have installed management tools in any other machine make sure to upgrade those also.
Finally: - how to verify the upgrade.

Goto Powershell and type below command.

GCM exsetup |%{$_.Fileversioninfo}
