After changing the LSN pool configuration while port blocks are active, the port blocks may become invalid because they are no longer be in the pool. An active port block may also become invalid if a translation request occurs during the short period of time between when a block expires and when we process the expiration. These invalid blocks are incorrectly counted in the 'Active zombie port block' count. Since the invalid blocks are not zombie blocks, the count is not decremented when the invalid block expiration is processed.
The PBA zombie statistics for the lsn-pool may be invalid.
More than one lsn-pool with overlapping address spaces, and virtual servers using these lsn-pools. Zombie timeout must be enabled on the pool and there must be active zombie port blocks.
The system can now invalidate an active port block if a translation request occurs during the short period of time between when a block expires and when we process the expiration, so PBA zombie statistics for the lsn-pool are now measured correctly.
