Hi,

I would suggest to check the WAS configuration and heap size, along with these you can also have look into the below steps.

1. Validate global security has been enabled

2. Validate that a group / user as been mapped to each jazz group in the applications security section in WAS

3. Check to ensure the 4 required jvm custom properties have been enabled

4. Check the heap size

5.Check the value for Jazz_Home

For example :

Jazz_Home Value make sure no extra slash "/" have been added.

file:///JazzInstallDir/server/conf

For heap size:

If you need more heap size, then you can use the following setting, replacing {N} with the amount of memory to be used and {N/4} with 1/4 of the total memory. For example, if -Xmx is set to 8g, -Xmn should be set to 2g.
-Xmx{N} -Xms{N} -Xmn{N/4}

Hope this helps.
