Increase max number of ACTIVE requestors
Our system is crashing in production where it reaches the max load on Monday between 10 am to 2 pm. On analysing the PegaRules and Alert logs found 2 major issues:-
1. Some of the DB queries getting timed out which probably keeping the threads occupied resulting in thread dumps.
2. Number of active requestors (1081) exceeds configured limit of 400.
The heap size configured is 8 GBs.
Can we improve the performance by increasing the number of active requestors. But where it is configured? I've seen in service package there is option but where to configure for the web requestors.
What else can be done to improve the performance during the max load?

In addition to Abhishesk's suggestion, you need to review overall Production environment.
Specifically, it is required to review Production sizing, number of JVMs, heap size, thread pool connection etc.

Hi Abikash,
Thats mostly the server level setting where you have to increase max thread pool size in the Work manager of app server.
Thank you

Thanks Abhishek and Arvind for the comments. The hardware sizing review is going and it will probably take some time to complete.
Meanwhile, Is there any setting in Pega or JBOSS you can suggest which I can edit and test?
Pega is running on JBOSS application server.
