Error 823, I/O errors 59 and 64

  • I would greatly appreciate if someone could please advise regarding the following:

    We have a non-critical database (I'd like to drop) on a SQL 7 production server.

    The event log is flooded with messages such as those below.

    I cannot drop (the referenced) claims_backup database, I cannot drop logins (from the master db) (get i/o error 59).

    In Enterprise Manager, I right-click on a mission critical table (different database) I get communication link failure error. Our backups started to fail about the same time these errors began to appear in the event log.

    The claims_backup.mdf is physically located on the sql server but the path referenced in the messages is a unc path. I don't know how to look at the database config to see if the referenced path is physical or logical (I suspect this might have to do with the problem). When I try to run sp_helpdb I get the i/o error 59 shown below.

    Error: 823, Severity: 24, State: 1

    Thank you for any assistance you can provide.

  • This was resolve by rebooting the server.

    Sorry guys - i should have tried the reboot before posting.

    By the way, the "faulting" database was setup w/ a unc path to the data and log files.

    All others had a physical path.

    I was able to drop the db after the restart and the sql server behavior has returned to normal.

    Thank you
