So the problem record is:
> rmgr: Gin len (rec/tot): 2/ 412, tx: 193820712, lsn: 24DB/72095E50, prev 24DB/72095CC8, desc: INSERT
isdata:F isleaf: T isdelete: T, blkref #0: rel 1663/16400/18030 blk 368350
for which you got this message:

00000000000024DB00000072,offset 614400
This is very odd. 24D9/23096000 looks like a valid address, perhaps
something that was left uninitialized from a previous write rather than
random corruption.
I don't suppose you can reproduce this at will, can you?
