Unpublished Bug 9703463 - ORA-3137 [12333] or ORA-600 [kpobav-1] When Using Bind Peeking
This bug affects versions 11.1.0.6, 11.1.0.7, and 11.2.0.1 of the RDBMS. It is fixed in version 11.2.0.2 of the database.
It can also occur intermittently; similarly to unpublished Bug:8625762, this is a bind peeking bug.
Unpublished Bug:9243912 - Additional diagnostics for ORA-3137 [12333] / OERI:12333
This bug affects versions of the RDBMS lower than version 11.2.0.2. It is fixed in version 11.2.0.2 of the database.
This bug addresses scenarios in which the ORA-3137 [12333] error occur bind issues during the client/server communication process. When this particular bug is fixed, the result may be the uncovering of an additional, more descriptive error: ORA-600 [kpobav-1]
你数据库版本较低，建议升级到11.2.0.4的最新

有用 0这个问题可能与之前提到的两个BUG相关，可能与变量窥探相关，麻烦确认一下隐含参数是否配置，如果没有配置的话，建议设置一下隐含参数来规避BUG，或者升级至更高版本。
