SSAS Issue on Cube refresh gives "Subscription identifier is invalid"

Hello,

Could you please help us on issue below:

When we process cubes by SSIS batch, we occasionally bump into the below error:

"The Subscription identifier is invalid; it must be unique when subscribing and the identifier of a registered subscription when unsubscribing. "

This is an erratic error and can happen on any of our cubes (20+). Our temporarily solution is to relaunch manually the processing of each cube facing this error.

Thanks in advance.

    Hi MICHAEL DIJKMAN ,

    Thanks for reaching out to SQL Q&A Forum

    1. Reduce processing concurrency Throttling cube and partition processing (instead of launching many objects in parallel) often reduces how frequently this issue occurs. Higher concurrency increases the likelihood of hitting the internal race condition.
    2. Add automatic retries This is the most effective mitigation. Catch failures in SSIS and retry the Analysis Services Processing Task after a short delay. In most cases, the retry succeeds immediately.
    3. Logging and diagnostics Increasing SSAS logging can help confirm timing, but historically this error has not yielded a clear root cause even with verbose diagnostics, suggesting an internal engine issue.
    4. Keep SSAS updated Staying current on cumulative updates is recommended, but this issue has been reported even on fully patched SSAS 2019 and 2022 systems.
    5. Monitor resource pressure High CPU or memory pressure can increase the frequency of intermittent engine errors, so ensure adequate resources and consider scheduling processing during quieter windows.

    Hope this helps!,

    Thanks,

    Lakshmi.
