> h6. Issue
> RocksDBStore is not closing WriteBatch native handles and under heavy write with multiple databases, following error is continuously throwing and database never recovers (following error is from infinispan 9.2.5-Final but i believe same issue exists in master , see https://github.com/infinispan/infinispan/blob/1bcfe5823e7957060080741f7d06f343c3447699/persistence/rocksdb/src/main/java/org/infinispan/persistence/rocksdb/RocksDBStore.java#L756)
> {code:java}
> Caused by: org.rocksdb.RocksDBException: unknown WriteBatch tag
> at org.rocksdb.RocksDB.write0(Native Method)

> at org.infinispan.persistence.manager.PersistenceManagerImpl.lambda$writeBatchToAllNonTxStores$12

> I was also getting other errors from this list, for example "bad WriteBatch Delete"https://github.com/facebook/rocksdb/blob/cae22c53fbad071be8aa3a8543415383b4dfaef4/db/write_batch.cc#L302
> h6. Fix
> {code:java}
> private void writeBatch(WriteBatch batch) throws InterruptedException, RocksDBException {
>     semaphore.acquire();
>     try {
>         if (stopped)
>             throw new PersistenceException("RocksDB is stopped");
>         db.write(dataWriteOptions(), batch);
>     } finally {
>         semaphore.release();
>         batch.close();
