Microsoft Exchange RPC Client Access fails due to high memory usage in Microsoft® SharePoint® Search Component (aka noderunner.exe) on Exchange 2013

After installing exchange 2013 and migrating clients over to the server you may notice Microsoft® SharePoint® Search Component or noderunner.exe running multiple instances with high memory usage. This is because Microsoft has integrated parts of sharepoint into exchange 2013. This process runs when accounts are first migrated and periodically to index email data stores for OWA in order to make search results fast, very fast.

You can disable Microsoft Exchange Search Host Controller service if it is causing an issue. In some cases it can consume an extremely high amount of memory causing the "Microsoft Exchange RPC Client Access" to fail and get stuck in a starting state. In which case the best solutions are to:

  • Increase the amount of RAM on the server.
  • Set the server to restart when "Microsoft Exchange RPC Client Access" fails. 
  • Disable the "Microsoft Exchange Search Host Controller service".

This is an obvious flaw in the design of exchange 2013 server.

Step by Step static network setup for CentOS 7.x on Microsoft Hyper-V Server using Linux Integration Services Version 4.0.11

Create new VHD with a standard Network Adapter

Download CentOS-7-x86_64-Minimal-1503-01.iso (insert disk & install)

Download lis4-0-11.iso (insert disk)

mkdir -p /mnt/cdrom
mount /dev/cdrom /mnt/cdrom
cp -rp /mnt/cdrom /opt/linux_ic4011
umount /mnt/cdrom
cd /opt/linux_ic4011/RHEL71
./install.sh

Once the install is done, reboot the VPS

Update your network settings via vi

vi /etc/sysconfig/network-scripts/ifcfg-eth0

use "i" to insert text, (esc) to exit and ":wq" to write your changes.

It should look something like this:

DEVICE="eth0"
BOOTPROTO=none
ONBOOT="yes"
TYPE="Ethernet"
HWADDR=(MAC ADDRESS, This should match what is configured in Hyper-V)
IPADDR=(YOUR SERVER IP)
GATEWAY=(YOUR DEFAULT GATEWAY)
DNS1=(PRIMARY DNS SERVER IP)
DNS2=(SECONDARY DNS SERVER IP)
Networking=yes


If your system is still not online for static IP do this:

 ifconfig eth0 (IP) netmask (MASK) up

 service network restart
