Hi Bonny. Probably you encountered the bug as bellow. 130051 A BLOCK W/ CORRUPT BLOCK HEADER IS REMOVED FROM BLOCK LIST BUT NOT FREELIST. WHEN ALLOCATING FROM FREELIST, BLOCK NOT ON BLOCK LIST -> CRASH This is no work around. If possible, upgrade 7.31.UD3 or later. HTH. -- Tsutomu Ogiwara from Tokyo Japan.
