Problem Description

After 248 days of system uptime the Cisco CallManager service and the Cisco CTIManager service will crash.

Background

Cisco Unified Communications Manager has an internal system timer that monitors system uptime along with other components. Cisco has found that once this internal timer value reaches 248 days, the internal value is mis-handled, causing Cisco CallManager and Cisco CTIManager services to crash.

Problem Symptoms

If the system reaches 248 consecutive days of uptime, the CCM and CTIManager system services will crash, resulting in a loss of call services and JTAPI services.

Directly before the event a message Avoided negative deltaTime will print in the CUCM SDL traces. There is no indication of this message in the RTMT or event logs.

Workaround/Solution

Workaround:

It is recommended that customers schedule a reboot of affected nodes before 248 days of system uptime elapses (since the last reboot).

Note: You must reboot the server to restart the timer to 248 days. Cisco CallManager or Cisco CTIManager service restarts alone will not reset the timer.

To verify system uptime, perform the following CLI command on each node in the cluster.

show status

The Cisco Unified Communications Operating System Guide provides information about using the Cisco Unified Communications the command line interface (CLI) to perform many common system- and network-related tasks.

Solution:

This issue is addressed in the following Cisco Unified Communications Manager versions and beyond:
-5.1(3d) which numerically is 5.1.3.5000-3
-6.1(2)SU1a which numerically is 6.1.2.1002-1

Customers running Cisco Unified Communications Manager 5.0.X or 5.1.X must upgrade to Cisco Unified Communications Manager 5.1(3d). Cisco Unified Communications Manager 5.1(3d) can be found at the following location:

Cisco Unified Communications Manager 5.1(3d) (registered customers only)


Customers running Cisco Unified Communications Manager 6.0(X) or 6.1(1) must install Cisco Unified Communications Manager 6.1(2), then proceed to install Cisco Unified Communications Manager 6.1(2)SU1a.

Cisco Unified Communications Manager 6.1(2) can be found at the following location:

Cisco Unified Communications Manager 6.1(2) (registered customers only)

Customers running Cisco Unified Communications Manager 6.1(2) must install Cisco Unified Communications Manager 6.1(2)SU1a. Cisco Unified Communications Manager 6.1(2)SU1a can be found at the following location:

Cisco Unified Communications Manager 6.1(2)SU1a (registered customers only)

Note: Prior to installing 6.1(2)SU1a, all nodes in the cluster must be on 6.1(2).
