The fix is to set the variable MAX_NBR_PARALLEL_ACTIONS to a value greater than the default value of 10.
with OVO 8, the variables are no more set in the opcinfo/opcsvinfo files. On the agent reporting the error, use the command ovconfchg -edit and add a line : MAX_NBR_PARALLEL_ACTIONS= in the [eaagt] section, then restart the OVO agent.
Extract from the HP document describing the error : PROBLEM
I'm trying to run a script on my box that fixes a mail problem when a message comes in and then it executes an automatic action. This action spawns off a script that is executed until the problem is fixed. When ITO spawns off 11 actions and the first 10 are still executing, I notice that the 11th script does not get started.
How do I run the 11th script (more than 10)?
