[jira] [Commented] (CONNECTORS-1447) Crash Agents A and B - can't
release lock we don't hold
[ https://issues.apache.org/jira/browse/CONNECTORS-1447?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16114144#comment-16114144 ]
Karl Wright commented on CONNECTORS-1447:
-----------------------------------------
Hi,
The core issue here is this:
{code}
Caused by: java.io.IOException: Unexpected packet type: 114
at org.postgresql.core.v3.QueryExecutorImpl.processResults(QueryExecutorImpl.java:1981)
at org.postgresql.core.v3.QueryExecutorImpl.execute(QueryExecutorImpl.java:257)
... 5 more
{code}
I believe this is coming from the postgresql JDBC driver. I note you are using Postgresql 9.6; the driver we include is the following:
{code}
<property name="postgresql.version" value="9.1-901.jdbc4"/>
{code}
I will look towards updating the driver we ship. In the meantime, I suggest you download a postgresql driver compatible with 9.6 and replace the one you are using with that one. Please let me know if that fixes your problem. Thanks!
