>SYNOPSIS: System Panics with: 'freeing free frag' or 'freeing free inode' or
> 'freeing free block'
>
>DETAIL DESCRIPTION:
>
>The system panics with one of the following messages:
>
> freeing free frag
> freeing free inode
> freeing free block
>
>SOLUTION SUMMARY:
>
>These panic strings are indications of corruption in the super block,
>the inode cache, or a race condition during file system operation.
>These corrputions or race conditions might have occurred for a number of
>reasons. Its resolution, for most cases, would require long in-depth analysis.
>
>To prevent any further corruptions, IMMEDIATELY fsck the file system
>that is having the problem. Use fsck with the "-o f" option to force
>a file system check. Save the results from the FSCK for later analysis.
>
>fsck will repair the damaged portion of the file system. Core files from the
>panic, most of the time, show only the afte-effect of the damage. The cause
>of the corruption or race condition, usually, cannot be determined until after
>tracing or debugging code is placed in modules that relate to the file system.
>
>If the fsck is not successful, instruct the customer to record the output
>messages from the fsck and relay them to you.
