I'm not sure if this has been solved, but you are hitting a known issue in Java version 8.0-6.35, which causes the stdSplitFreeListSplitAmount error. There is a confirmed issue where ibm-java-x86_64-sdk-8.0-6.35.x86_64 doesn't work due to a JVM configuration problem and the service cannot start.

What to do:

Option 1. Contact Support to report this issue, if you have not done so already.

Option 2. You can try to downgrade the Java version on your host where DLC is installed to 8.0-6.30.x86_64. Then try to restart the DLC service: systemctl restart dlc

I would probably talk with support first, to ensure that your case is added to this known issue for DLC. If you do open a case, I would include this forum post as a reference. The support rep can confirm you've got the proper Java version in case things have changed since I responded to this forum post.
