Task fails at runtime with error: Task initialisation failure, error code 0x80040300

Table of Contents

Symptom #

When a task contains many connection steps an initialisation failure can occur. The following system error is recorded to the event log:

Error code: 0x80040300
Description: Task initialisation failure

This can occur when the following types of connection steps are in use:

  • Web Service Connector
  • Database Query (ODBC or OLEDB)
  • External Memory (ODBC or OLEDB)

Cause #

The number of connections steps in the task is set by a unique number called a ContextHandle. The default ContextHandle limit is 10. When this number is exceeded, the fault mode occurs.

Applies To
 #

TaskCentre v4.1 (Build 300) to 4.5 SR4I (Build 2015)

Resolution #

Increase the allowable number of connections steps, by increasing the ContextHandle limit. The recommended value is 100.

  1. Navigate to the TaskCentre registry key
    On 32 bit systems:
    HKLM\SOFTWARE\Orbis Software\TaskCentre
    On64 bit systems:
    HKLM\SOFTWARE\Wow6432Node\Orbis Software\TaskCentre
  2. Add a new DWORD value  called ContextHandleAllocation and set its data to 100. The TaskCentre Server service will need to be restarted to pick up the change.
