My company has setup a DMS developed by a software house. We know that it's embedded with Jackrabbit 1.5.3. About one year ago, the vendor increased the MergeFactor to 30 because we reported the performance became worse. Actually, after the change, we didn't notice any significant improvement. In these few months, we found the system sometimes reports OOM (java heap space). It usually happens when using the batch import function of our DMS. After reading some articles about merging of jackrabbit,I suspect that the increased MergeFactor may be the cause of OOM. Is it possible? And could we get rid of the OOM problem by lowering the setting?
