kpoal8()看网上介绍这个位置应该是个内部函数,连metalink搜索的时候都是"ora-7445 kpoal8"

google了很多，很多都是说SQL引起的，看到这句Current SQL statement for this session:我也真信了，
但是转换一下，发现:

The stack from the ORA-7445 trace file looks similar to:"kpoal8 opiodr ttcpip opitsk opiino opiodr opidrv sou2o opimai_real main"
Solution is to upgrade the 9.2.x client to at least 9.2.0.4.0.
