Re: Help desperately needed: reoccurring invalid page

Mauri, I'm no expert but I can tell you what I know.  We
have experienced this same problem, and I asked a
similar question not too long ago.

-  This is probably due to some sort of I/O problem.  In
   our case, it occurs very frequently on reboots, and
   it appears to be related to dirty buffers not being
   flushed out when the partition is unmounted.  Look
   into a newer kernel, and/or newer/different
   filesystem (we have seen this in various flavors
   of the 2.4.6 kernel with XFS, JFS and EXT3).

-  If you have invalid page headers, you should take a
   look at the run-time parameter zero_damaged_pages.
   You can use this to fix up a table (losing the data
   on the bad pages).

-  We have not found a way around the missing log file
   problem.  This appears to end up locking some rows
   forever.

Others on this list may be able to tell you about tools
for examining/fixing corrupt tables and log files.
