>Cliff,
your OS or hardware has probably corrupted the ibdata file.
Ouch!
Next record offset is nonsensical 28769 in record at offset 7022
Before writing an index page to the file, InnoDB checks that offsets are sensible (< 16 kB).

Hmm... the 'old checksum' at offsets 16 kB - 8 ... 16 kB - 4 is zero. That is probably file corruption.

The printout looks like you tried a downgrade and upgrade of MySQL to resolve the crash? Is that true? Which 4.1.x version you are running?
Yes, initially I had thought that there was an issue with the installation itself, so I upgraded to v4.1.7-0.
Please send the FULL .err log to me [EMAIL PROTECTED] for more detailed analysis. Do not cut anything off.
Unfortunately the mailing list stripped your domain off. Please send an email to spam at cjs226.com and I'll send you the err log.
Your lsn is only 300 MB. High-end users of InnoDB on a stable Linux computer can easily reach 300 GB without any corruption.

Everything was fine...I haven't installed anything lately, etc. I've got a Fedora FC1 system running MySQL v4. I noticed my db exports failing this morning. The db wasn't running and now won't startup. I'm googling but... Here's what's in the log:

This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.
We will try our best to scrape up some info that will hopefully help
diagnose
the problem, but since we have already crashed, something is definitely
wrong
and this may fail.
key_buffer_size=0 read_buffer_size=131072 max_used_connections=0 max_connections=100 threads_connected=0 It is possible that mysqld could use up to key_buffer_size + (read_buffer_size + sort_buffer_size)*max_connections = 217599 K bytes of memory Hope that's ok; if not, decrease some variables in the equation.
76 thd=(nil) Attempting backtrace. You can use the following information to find out where mysqld died. If you see no messages after this, something went terribly wrong... Cannot determine thread, fp=0xbff3ecb8, backtrace may not be correct. Stack range sanity check OK, backtrace follows: 0x808d737 0x82e17a8 0x825f3dd 0x825ee95 0x820d264 0x820e2c5 0x81f2751 0x8231a83 0x813ed39 0x82def5c 0x83088da New value of fp=(nil) failed sanity check, terminating stack trace! Please read http://dev.mysql.com/doc/mysql/en/Using_stack_trace.html and follow instructions on how to resolve the stack trace. Resolved stack trace is much more helpful in diagnosing the problem, so please do resolve it The manual page at http://www.mysql.com/doc/en/Crashing.html contains information that should help you find out what is causing the crash. 77 78 041116 17:17:10 mysqld ended <end of log>

But I'm just sad sys admin reading greek at this point... Any ideas?
