​Unable to open jobs with error "Unable to open the Job Unable to load RID - c2e76d84.43058877.7e01af4f.cd92bbcd-2ebc-4cb3.833e.37a962373ef7"

Also in SystemOut.log file, it has the following:
[8/25/10 21:21:46:475 UTC] 000000b1 SystemOut O 2010-08-25 21:21:46,475 ERROR ojb.OjbPersistentEObjectPersistence - java.lang.OutOfMemoryError



Solution :

1) Try to restart the DS Client and reopen the job

2) Increasing Java Virtual Machine (JVM) Heap will resolve this problem. Here are the steps to do this:

    Log into the WebSphere Application Server administrative console.
    Select Server > Application Servers and select the <ServerName>.
    In the Configuration tab, navigate to Server Infrastructure > Java and Process Management > Process Definition > Additional Properties: Java Virtual Machine
    Edit the field Maximum Heap Size. If the default is not specified then it assumes 256.


Note: A value greater than 512 MB will improve the performance of the Data Collector. ​

BLAFS is a bloat-aware filesystem for container debloating. The design principles of BLAFS are effective, efficient, and easy to use. It detects the files used by the container, and then debloats the container by removing the unused files. The debloated containers are still functional and can run the same workload as the original containers, but with a much smaller size and faster deployment. https://github.com/negativa-ai/BLAFS?tab=readme-ov-file
