Subject: Why does JDBC application logging SQL instructions in Apache Tomcat
 lists 545 repeatedly

I'm not sure of this is an Apache Tomcat issue or not but here goes: I am currently running a number of programs in 
batch which dynamically create and populate a number of tables in MySQL Server Version 5.5. 

When I do this, I am logging the SQL to an Apache Tomcat log file. Sometimes the SQL listings 
will list a particular series of queries reading the <title> elements of RSS feeds one by one such as:
  
    SELECT TITLE  FROM _rss_172_917617_01012011_1293889632011 WHERE CreatedDateTime BETWEEN '2011-07-01 00:00:00' 
AND '2011-07-31 23:59:00';
    SELECT TITLE  FROM _rss_173_353205_01012011_1293889643042 WHERE CreatedDateTime BETWEEN '2011-07-01 00:00:00' 
AND '2011-07-31 23:59:00';

Then the name of the system will be printed as follows in the log file:

    [myApp]

And then there will be a series of lines reading:

    545

Before the next series of queries run. And when the next series of queries does run, the text of each query is 
listed, and then another line lists the system name.

    SELECT TITLE  FROM _rss_121_298920_24122010_1293174184748 WHERE CreatedDateTime BETWEEN '2011-07-01 00:00:00' 
AND '2011-07-01 23:59:00';
    [myApp]

MyApp is written in Java and running under Tomcat 6.0.26. I should add that sometimes the number of queries 
producing the data for one table, which may number in the hundreds, appear to be fine. Other times the 545 message 
is listed: this appears to be sporadic with no apparent pattern.

Though the queries appear to be running, can anyone tell me what 545 might mean? It seems to happen on two separate 
servers running the same programs but over different data.
