oracle 内部错误ORA-07445:

chinadm123

早上八点半左右客户oracle的应用均无法连接。他们无奈重启机器后一切恢复正常，上午我去收集一些报错信息。
环境：HPUX 11.23
oracle:RAC 环境，原来是9204，去年去给他们升级到9208了。
查看alert日志发现上午出现问题的时候有报错，在节点一上：下面的信息均为部分信息，详细报错信息见附件。

在看了群主的ORA-07455系列之后依然没有啥思路，苦于没有mos账号也不太方便。现在将信息提供给大家练练手，多多指点！
虽然有其它报错比如“ORA-1652: unable to extend temp segment by 128 in tablespace                 TEMP ”，根据此错出现时间与oracle出问题来分析是ORA-1652先造成的可能性较小，不至于造成应用都连不上的情况。
