Symptom:
In LiveUpdate Administrator (LUA) 2.x a Distribution schedule will not start, whether by schedule or manually with the Run Now button. Previously the task had been running at its scheduled time, but now, for no obvious reason, when scheduled to run it just fails.
Troubleshooting:
In the LUA interface, under Events, look for an error message similar to: “Execution for schedule <schedule_name> is skipped because already running request found for this schedule.” [sic]
The Activity Monitor shows no schedule is running.
Cause:
The error message indicates that a scheduled task did not close properly, which is preventing the next scheduled run from being able to start. The hung task is not visible or does not exist.
The hanging schedule can be either a Distribution task or perhaps a Download task.
Solution:
Log off the LUA interface and restart the LUA host server.
Additional:
If you have alerts configured, you may receive an email like this after the restart:
