是因为Connection Nr[0]
具体错误（在Executor-7033-20150407-163826.trace文件中）
10:39:39.550-1073824092- DataBaseHelper::open-INFO-DataBaseHelper.cpp[106]-Connection Nr[0]
应该为
16:38:26.424--134334400- DataBaseHelper::open-INFO-DataBaseHelper.cpp[106]-Connection Nr[1]
0:45:44.772--134334400- DataBaseHelper::open-INFO-DataBaseHelper.cpp[106]-Connection Nr[1]
20:45:44.772--134334400- DataBaseHelper::open-INFO-DataBaseHelper.cpp[171]-Analysing FileSsystem Connection
因为[106]出了问题，所以[171]没有执行，即，[111]行的 for 循环的 循环体 没有执行。
下面调试，找问题
(gdb) break DataBaseHelper.cpp:236
(gdb) break DataBaseHelper.cpp:109
