What OS?
Could it be that you have attempted to write past the end of the virtual disk?

Here is the OS version:
Linux msscys091 2.6.18-92.el5PAE #1 SMP Tue Apr 29 13:31:02 EDT 2008 i686 i686 i 386 GNU/Linux

I am not writing anything, what ever the command I issue in the database server I am getting this error message which in turn i have to close the session and reopen the same and unable to perform any operations. Let me know if you need any more information to resolve this issue.

Thank you.

Sounds like you have a hardware problem(i.e. disk drive), Run( or have your systems person ) run diagnostics on the drives, also google some of the errors from your log:
