客户现场出现一个问题，我在Java代码中只调用了一次SQL，正常情况下执行一次，跟踪日志中打出一行sql语句就完了；现在问题是跟踪日志中重复不断的打出sql语句，不知道成功执行了几次。跟踪日志贴出来如下：

....
正常情况下执行的日志应该是：
2014-03-07 08:25:47,973 DEBUG - [3018]MetadataPresentingDAO.createMetaData(): add metadata finished
2014-03-07 08:25:48,020 INFO - [3018]NAV Write WQ SQL=INSERT INTO WQ_INFO (QueueUID,Source_type,local_entry_UID,Parent_HUID,Entry_Name,Entry_type,Operation_type,Operation_time) VALUES ( N'W14397490',2, N'0', N'0', N'0',5,99,'2014-03-07 08:25:48')
2014-03-07 08:25:48,020 INFO - [3018]Execute Result=1

2014-03-07 08:25:48,192 INFO - [3018]ProgramPresentingDAO.existProgram(): affectedRows=1
即这条语句执行前后都会有其他语句执行。
这种不正常的现象足足持续了两天，日志中也一直打印上述语句，不时还出现其他线程的日志，但是线程号都是一样的，后来就出现内存溢出，日志如下：
2014-03-07 04:42:26,611 DEBUG - [1093][LAM] LamConfigManager->getConfigValue From ConfigApp ( MasterPort ) return 8080
