Hi ,
We have started Se Garbage Collection and S3 size is more than 2 TB.
We are facing memory issues while executing GC even when we have given 11 GB of
memory to the application.

final MarkSweepGarbageCollector gc =
documentNodeStore.createBlobGarbageCollector(seconds, repository.toString(),
wb, new DefaultStatisticsProvider(Executors.newScheduledThreadPool(1)));
gc.collectGarbage(markOnly);
final OperationsStatsMBean stats = gc.getOperationStats();
log.info(
"number deleted : " + stats.numDeleted() + " Size deleted : " +
stats.sizeDeleted());
The exceptions are :

It might be necessary to set the fetch size (see

Sorry, can't test that right now myself.
Best regards, Julian
