Anyone seen this one...

I have a user running SQL against a database, she keeps getting disconnected. After the 3'rd time we get a block corruption error. I was actually getting disconnected from a database yesterday while re-running catproc.sql. The db was hosed and so was soem disk so we decided to rebuild since it was not previously under our control, I ignored it for the time being. This is a completey different database and server (8.1.6 on Sun). I think she was running SQL*Plus on her client.

Here is the corrupted segment...

TABLESPACE_NAME                SEGMENT_TYPE       OWNER

SEGMENT_NAME

SYSTEM                         INDEX              SYS
