Pega becomes unstable.
We are currently upgrading Pega from 7.3.1 to 8.7.2. With 8.7.2, Pega's application server becomes unstable, causing the following issues Data type import does not work. Export of products does not work. SLA does not work. The problem can be resolved by restarting the application server, but will recur after a period of time.
Do you have any information on this issue?

Hi @makotok7, Were you able to find the issues from logs? How big is the data type you are importing and how bug is the product which you are exporting.
Other possible issues may
- Heap allocated to the node
- Check if you have proper stream node created
Thanks

Hi,
If you're using Pega in On-Prem:
1. Try to Analyze the Provided Heap Size and usage and allot more based on the Usage analysis.
2. Once the Application is doing better, You'll need to generate Thred Dumps along with Heap dumps.
3. Make sure Stream Node is the only JVM Argument configured as stand alone Node type and Increase Stream Nodes to 2 / 3 upon your hardware sizing and Usage of it.
If you're using Pega in Cloud / Containerization Tools:
1. You can directly alter the Stream POD size from the Deployment file
2. You can also alter the Heap Size allocation from the same Deployment file.
Common thing:
1. Pega Application becomes unstable if you have not configured the parameter (-Djava.security.egd=file:///dev/urandom) in the Deployment Configurations.
2. No Matter, whatever the amendments and size allocations you do if you did not configure the above parameter. Issue will be keep coming your way.
