We are running Jboss4.0.2. We use it for queuing as well as maintaing connection pool to the database. Occasionally we see (lots of when it happens) below error in the logs. anonymous wrote : | 19:34:32,947 WARN [TransactionImpl] Transaction TransactionImpl:XidImpl[FormatId=257, GlobalId=cmp2app01/47048438, BranchQual=, localId=47048438] timed out. | status=STATUS_ACTIVE | 19:34:32,951 WARN [TransactionImpl] Transaction TransactionImpl:XidImpl[FormatId=257, GlobalId=cmp2app01/47048446, BranchQual=, localId=47048446] timed out. | status=STATUS_ACTIVE | 19:34:32,951 WARN [TransactionImpl] Transaction TransactionImpl:XidImpl[FormatId=257, GlobalId=cmp2app01/47048449, BranchQual=, localId=47048449] timed out. | status=STATUS_ | | What does above mean and what can be the impact ?

What could be the cause and where should I be searching for solutions? Also is there any relation between connection pool for hypersonic DB and oracle DB? I have seen that usually DB connection problem occurs whenever we hit a problem with hypersonic DB in production. When the problem strikes we usually see that the sum of available and used connections doesn?t even sums up to the max configured in oracle-ds.xml Any idea/suggestion would be really helpful.
