Steps to reproduce the OOM error:
./gradlew generateBlockchainReferenceTests
BlockchainReferenceTest_455.java
setprivate static final String[] TEST_CONFIG_FILE_DIR_PATH = { "BlockchainTests/GeneralStateTests/stTimeConsuming/static_Call50000_sha256.json" };
./gradlew reference-tests:referenceBlockchainTests --tests "BlockchainReferenceTest_455"
The test case
static_Call50000_sha256_*
inBlockchainReferenceTest_455
causes the JVM to run out of heap space. Increasing the heap to 24G worked for me.In this test
ZkTracer.traceContextEnter
is invoked 50000 times (Don't know why), and inside this methodthis.hub.traceContextEnter(frame)
consumes up all the heap.
