ICM 11.0(2)
ICM11.0(2) ES4 is compatible with and should
be installed on these ICM components:
Do not
install this engineering special on any of the following components other than:
·
Installation of this patch requires the all ICM services to
be shutdown during the entire period of installation. It is always
recommended to install this ES during a scheduled downtime.
·
Using the ICM Service Control, stop all the ICM services
running on the system
·
Launch the Installer provided for ES4 and following the
instructions on the screen
·
Using the ICM Service Control, start all ICM services
again.
To uninstall this patch, go to Control Panel.
Select "Add or Remove Programs". Find the installed patch in the list
and select "Remove".
Note: Patches have to be removed in the
reverse order in which they were installed. For example, if you had installed
patches 3, then 5, then 10 for a product, you will need to uninstall patches
10, 5 and 3 in that order to remove all patches for that product.
This section provides a list of significant
ICM defects resolved by this engineering special. It contains these

Note: You can view more information on and track individual
ICM defects using the Cisco Bug Toolkit located at: http://www.cisco.com/support/bugtools/Bug_root.html
This section lists caveats specifically
resolved by ICM11.0(2) ES4.
Caveats in this section are ordered by ICM
component, severity, and then identifier.
Be sure to include ALL of the resolved caveats for the files you're delivering,
i.e. all of the caveats from the release notes of the previous ES which included these files.

Defect Number: CSCuy57986
Component: router
Severity: 2
Headline: RTS does not reconnect after router failure (large
deployment)
Symptom: RTS is consuming 25% of the CPU and
cycling every 5 minutes
Conditions: ICM Router failover and attempting to recover
Workaround: Follow these steps for both routers and all distributors:
1.
Stop Router service.
2.
Increase the BufferMaxQueue value to 10000 HEX in the
following registry: RouterA\RealTimeServer\CurrentVersion\BufferMaxQueue
3.
Increase the BufferMaxQueue value to 10000 HEX in the
following registry: Distributor\RealTimeDistributor\CurrentVersion\BufferMaxQueue
4.
Increase the SendMaxQueueLimit value to 100000
DECIMAL in the following registry: RouterA\MDS\CurrentVersion\Process 5. Start Router service.
Further Problem Description:
The router failover scenario
caused router process to resend the burst of real time data messages to RTS process which caused:
1. The MDS process
disconnecting the RTS client was due to the buffer queue depth over flow when
sending real time data messages from Router to RTS process.
2. The RTS process
disconnecting RTD clients due to the buffer queue depth overflow when sending
real time data messages to RTD process on the distributor.
Defect Number: CSCuy30311
Component: pg.opc, router, dbagent, logger
Severity: 3
Headline: State Transfer performance and reliability impacted
by large state sets
Symptom: Process taking long time (30+ minutes)
when side other side is restarted, on large environments (12K, for instance).
This affects typically Router and OPC, and, beyond dilates transfer time, it
can lead to process crash due to OOM.
Conditions: State transfer process (Router, OPC, Logger, etc) under load (typically on 12K environments) and other
side is restarted. Also possible if/when user attempts to perform checksum
operation while load is in progress.
Workaround: None.
