cache line is no
longer in use
At least one line in the cache is no
longer in use due to excessive ECC
errors detected during use of the
memory associated with that cache
line.
Replacement of cache should be considered. If
cache replacement is not done, remaining
cache lines should continue to operate properly.
Accelerator
status: Obsolete
