Hippo CMS 12.6.8 uses too much RAM suddenly what could cause it?

1

Hi all, i’m running Hippo CMS 12.6.8 for a small project
Sometimes memory usage suddenly spikes close to 8 GB even though

What could cause this?
Could it be indexing or something internal?
Also, is there a way to monitor what’s going on during these spikes?
Maybe some JVM flags I can enable when launching on my VPS server to help diagnose the issue?

Thanks very much

  • Hi @B_A ,

    The high memory usage in Bloomreach Experience Manager (CMS) is commonly caused by Lucene indexing bursts, oversized in-memory caches, or inefficient garbage collection configurations.

    1.Check for indexing bursts under /repository/logging/query/lucene with log level INFO.

    2.Reduce bundleCacheSize in your repository.xml if the project is small.
    3. Monitor GC logs — frequent full GCs or long pauses imply oversized cache regions.
