Deploying a large number of probes via Admin Console causes the UIM system to become unresponsive for a period of time.
The following components may become unresponsive and may display errors:
Unified Management Portal
During this time, the following log entries in controller.log on the primary hub may be seen:
Sep 12 15:13:38:567  Controller: nimSessionWait: more than 64 objects, checking again
This issue can be caused when automated_deployment_engine spawns more threads than the controller is capable of handling. This can be observed on primary hubs that have a large number of cores and the distribution list contains a large number of targets.
automated_deployment_engine calculates the optimal number of threads based on cpu resource available and incorporates a limiting factor.
At 2 cores, it will use 8 threads.
At 4 cores, it will use 18 threads.
At 8 cores, it will use 35 threads.
- Open automated_deployment_engine Raw Configure
- Click New Section
- Enter automated_deployment_engine
- Check Create at root
- Click OK
- Click the automated_deployment_engine section
- Click New Key
- Enter the key name of numThreads
- Enter a value of 4
It may be possible to increase the numThreads value higher than 4 in your environment. Increase the value slowly until the system exhibits the unresponsiveness issues again and then back that value down 10-15%.
