Shawn, first off thanks for the reply and links! "As far as the error in the 5.0.8 version, does the import work, or does it fail when the exception is thrown?" - The import "works" for about 5-10 minutes then it fails and everything is rolled-back one the above exception is thrown.
" You might also try doing as it says and increasing the timeout on the server" - How is this accomplished? I tried "maxWait" options on the datasource in data-config.xml but that didn't seem to work. I'm also torn on whether or not I should file a bug that may or not exist. The whole reason I tried downgrading to 5.0.8 was due to the fact that during certain (not all) delta-imports I keep getting the following error which seems to be all mysql related: SEVERE: Delta Import Failed java.lang.StackOverflowError at java.net.SocketOutputStream.socketWrite0(Native Method) at java.net.SocketOutputStream.socketWrite(SocketOutputStream.java:109) at java.net.SocketOutputStream.write(SocketOutputStream.java:153) at java.io.BufferedOutputStream.flushBuffer(BufferedOutputStream.java:82) at java.io.BufferedOutputStream.write(BufferedOutputStream.java:126) at com.mysql.jdbc.MysqlIO.send(MysqlIO.java:3296) at com.mysql.jdbc.MysqlIO.sendCommand(MysqlIO.java:1941) at com.mysql.jdbc.MysqlIO.sqlQueryDirect(MysqlIO.java:2114) at com.mysql.jdbc.ConnectionImpl.execSQL(ConnectionImpl.java:2690) at com.mysql.jdbc.StatementImpl.executeSimpleNonQuery(StatementImpl.java:1545) at com.mysql.jdbc.RowDataDynamic.close(RowDataDynamic.java:201) at com.mysql.jdbc.ResultSetImpl.realClose(ResultSetImpl.java:7624) at com.mysql.jdbc.ResultSetImpl.close(ResultSetImpl.java:908) at com.mysql.jdbc.StatementImpl.realClose(StatementImpl.java:2364) at com.mysql.jdbc.ConnectionImpl.closeAllOpenStatements(ConnectionImpl.java:1583) at com.mysql.jdbc.ConnectionImpl.realClose(ConnectionImpl.java:4454) at com.mysql.jdbc.ConnectionImpl.cleanup(ConnectionImpl.java:1359) at com.mysql.jdbc.ConnectionImpl.execSQL(ConnectionImpl.java:2723) at com.mysql.jdbc.StatementImpl.executeSimpleNonQuery(StatementImpl.java:1545) at com.mysql.jdbc.RowDataDynamic.close(RowDataDynamic.java:201) at com.mysql.jdbc.ResultSetImpl.realClose(ResultSetImpl.java:7624) at com.mysql.jdbc.ResultSetImpl.close(ResultSetImpl.java:908) at com.mysql.jdbc.StatementImpl.realClose(StatementImpl.java:2364) at com.mysql.jdbc.ConnectionImpl.closeAllOpenStatements(ConnectionImpl.java:1583) at com.mysql.jdbc.ConnectionImpl.realClose(ConnectionImpl.java:4454) at com.mysql.jdbc.ConnectionImpl.cleanup(ConnectionImpl.java:1359) at com.mysql.jdbc.ConnectionImpl.execSQL(ConnectionImpl.java:2723) .... and it keeps going Once the above exception occurs I can never delta-import again against that index. I am then forced to do a full-import. Do you have any thoughts or suggestions on that? Should I file this as a MySQL bug? Thanks again for your help. I'll try playing around with the latest versions of the connector and I'll post my results. -- View this message in context: http://lucene.472066.n3.nabble.com/Recommended-MySQL-JDBC-driver-tp817458p817790.html Sent from the Solr - User mailing list archive at Nabble.com.
