Search: lot of threads PegaRULES-Search[generic]

Hi,

We have an issue about Search function creating a lot of threads under Pega 7.1.8 on JBoss.

We have stopped the index agents but still more and more of these theads are created until they reached a system limit of created threads. Here what we can see in the SMA:

ServerService ThreadGroup         PegaRULES-Search[generic][T#98]            5         true         true         false           

ServerService ThreadGroup         PegaRULES-Search[generic][T#99]            5         true         true         false           

ServerService ThreadGroup         PegaRULES-Search[generic][T#9]            5         true         true         false           

ServerService ThreadGroup         PegaRULES-Search[index][T#1]            5         true         true         false

ServerService ThreadGroup         PegaRULES-Search[management][T#1]            5         true         true         false           

ServerService ThreadGroup         PegaRULES-Search[management][T#2]                    

...

Also I can see 3 Search categories : generic / index / management. It is the generic which is cretaing a lot of threads.

Do you know when and for what these threads are created ? Why threds are not reused (within thread pools) ?

How we can control the number of parallel threads and their pool size ?

Thank you for your help.

Best regards,

Halim
