Hi everyone,

We are getting an "Unknown device error" with code -305 in the event viewer on our ASA9 (version 9.0.1.1751) server. When it happens, nobody can connect to the database until we stop/start it. The failuer is accompanied by the following messages in our log file:

I. 12/06 13:46:32. A read failed with error code: (38), Reached the end of the file.
E. 12/06 13:46:32. Fatal error: Unknown device error
I. 12/06 13:46:32. Fatal error: Unknown device error


Our application logs the following:

Database error code: -305

Database error message:
Select error: SQLSTATE = S1000
[Sybase][ODBC Driver][Adaptive Server Anywhere]I/O error Fatal error: Unknown device error -- transaction rolled back


It looks like this may be an application problem, but I cannot find any documentation on an error -305, if anyone can help we would appreciate the assistance!

Thanks,
Terry Schmidt
