又是一个EXADATA上的错误。
数据库版本为11.2.0.2 RAC,错误信息为:
Tue DEC 06 10:34:33 2011 Exception [TYPE: SIGSEGV, SI_KERNEL(general_protection)] [ADDR:0x0] [PC:0x908F8BC, kghfrf()+94] [flags: 0x0, COUNT: 1] Errors IN file /u01/app/oracle/diag/rdbms/orcl/orcl1/trace/orcl1_ora_12085.trc (incident=42231): ORA-07445: exception encountered: core dump [kghfrf()+94] [SIGSEGV] [ADDR:0x0] [PC:0x908F8BC] [SI_KERNEL(general_protection)] [] Incident details IN: /u01/app/oracle/diag/rdbms/orcl/orcl1/incident/incdir_42231/orcl1_ora_12085_i42231.trc USE ADRCI OR Support Workbench TO package the incident.

根据MOS文档Bug 13780035 Updated fix for bug 13340182 to address additional ORA-7445的信息,这个bug是Oracle在解决问题一个bug时引入的,确认影响的版本包括11.2.0.3和11.2.0.2。Oracle计划在11.2.0.4和12.1中来FIXED这个问题。
不过这个问题并不是每次都可以重现,且并不会造成严重的后果,因此暂时没有解决的方法还尚可接受。
