经过查明，是ORACLE 11G的一个BUG，最终问题已经按照文档修改，是否解决需要观察。
根据ORACLE文档的解决办法：

There are 2 workarounds available:
1] Create the following directories under the $ORACLE_HOME/dbs:
    javanld1
    plsqlnld1
2] Disable the just in time compiler, set initialization parameter:
   java_jit_enabled = false
   
The permanent solution is to upgrade to 11.1.0.7 when it is released
NOTE:
When the workaround of creating directories is implemented, there will be a lot of small files generated under $ORACLE_HOME/dbs/javanld1 with name format:
JOXSHM_EXT_<nn>_TARSG1_0.so*
These files get deleted when the database is shutdown.
 
解决步骤如下：
SQL> show parameter JAVA_JIT_ENABLED;
NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
java_jit_enabled                     boolean     TRUE
$ cd $ORACLE_HOME
$ cd dbs
$ mkdir javanld1
$ mkdir plsqlnld1
SQL> alter system set JAVA_JIT_ENABLED= FALSE scope = both;
System altered.
SQL> show parameter JAVA_JIT_ENABLED;
NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
java_jit_enabled                     boolean     FALSE
