Internal Comments


The problem is happening when a checkpoint in an almost full and fragmented file system is being deleted. The fix is to make sure that the number of pages in transaction limit is not exceeded.



PLEASE NOTE:



Other issues are also resolved by upgrading per above:




6452655 Postmark performance severely degraded with release 4.12 build 20
6491929 volume erroneously reports it's full and is put read only by the head.


Please stress the importance of these fixes with your customers and encourage them to upgrade.
