Hi @SamuelBoerlin There seem to be several potentially different things going on here. 1. > ``` > Exception in insertPrefixes: Not in a transaction > org.apache.jena.dboe.transaction.txn.TransactionException: Not in a transaction > at org.apache.jena.dboe.transaction.txn.TransactionalComponentLifecycle.checkTxn(TransactionalComponentLifecycle.java:350) > at org.apache.jena.dboe.trans.bplustree.BPlusTree.getRootRead(BPlusTree.java:156) > . . . > ``` Do you happen to know what the CONSTRUCT query is? Have other CONSTRUCT queries succeeded? I think this is different problem but made likely to happen around the time of compaction finishing. It may (I'm still investigating) leave the system in a broken state but something triggered it in the first place. 2. > ``` > [12540] **** Exception in compact > java.lang.InternalError: a fault occurred in an unsafe memory access operation > at org.apache.jena.dboe.base.buffer.BufferBase.copy(BufferBase.java:84) > at org.apache.jena.dboe.trans.bplustree.BPTreeRecords.split(BPTreeRecords.java:211) > . . . ``` It's inside the JVM to get a `java.lang.InternalError` - it is accessing a memory mapped file. Would it be possible to run without `--add-modules=jdk.incubator.vector` and with a 2G heap `-Xmx2G`? -- This is an automated message from the Apache Git Service.
