Multiple chains with identical chain_id value in Backlog


Release: AAMOS499000-8.0-Automic Applications Manager-OS400 Agent


Detailed Description and Symptoms

In the rare occurrence of seeing multiple chains with the same ID in the backlog and viewing the AwE-9999 error message below:

ErrorMsg: AwE-9999 Internal error (10/12/10 7:56 PM)

Details: null

java.lang.IllegalArgumentException: backlog out of sequence

you have most likely encountered a known issue where the application has exceeded the allowed sequence numbers and needs to reset the value

The sequence number that we use to keep track of changes to the backlog has a maximum of 2,147,483,647. This is the maximum positive value of a 'signed int' in Java. However, java at times, makes incremental leaps (as opposed to progression by +1 for the sequence number) causing the sequence number to increase significantly. Because of this, the maximum limit may be reached quicker than expected.

The solution for this is to re-sequence this value. This will reduce the number significantly. 

A patch is being created for the latest version of AM that will increase the max value to greater than 1,000,000,000,000.
