Hi All,
We have hit the following problem when using MvStore 1.4.198
java.lang.IllegalStateException: An old transaction with the same id is still
open: 1 [1.4.198/102]
at org.h2.mvstore.DataUtils.newIllegalStateException(DataUtils.java:883)
at
org.h2.mvstore.tx.TransactionStore.addUndoLogRecord(TransactionStore.java:407)
at org.h2.mvstore.tx.Transaction.log(Transaction.java:306)
at org.h2.mvstore.tx.TxDecisionMaker.logIt(TxDecisionMaker.java:131)
at org.h2.mvstore.tx.TxDecisionMaker.decide(TxDecisionMaker.java:69)

org.h2.mvstore.tx.TxDecisionMaker$PutDecisionMaker.decide(TxDecisionMaker.java:199)
at org.h2.mvstore.MVMap.operate(MVMap.java:1670)
at org.h2.mvstore.tx.TransactionMap.set(TransactionMap.java:306)
at org.h2.mvstore.tx.TransactionMap.set(TransactionMap.java:289)
at org.h2.mvstore.tx.TransactionMap.put(TransactionMap.java:226)
The code that triggers this is:
Transaction tx = ts.begin();
TransactionMap<Long, AgreedProposal> map = tx.openMap(mapId);
old = map.put(agreed.getKey(), agreed);
TransactionMap<String, Long> highestKeyMap = tx.openMap(HIGHEST_KEY_MAP);
// We track the highest key we see.
highestKeyMap.put(highestSendKeyLookup, agreed.getKey());
tx.commit();
I found another post from someone who hit a similar issue but they had multiple
threads using the same transaction which we are not doing.
This only triggers when we do a load test of our application.
Any advice on how we could be triggering this, or how to debug? I am trying to
isolate it in a unit test.
I rolled back to 1.4.197 but got an "Entry is locked [1.4.197/101]" error.
I will test with 1.4.199 but I suspect it is some code change we did that is
triggering this.
cheers
Mark
