Subject: mysql with innodb not reliable
>Description:
011115 09:58:46 mysqld started
011115 9:58:48 InnoDB: Started
/usr/sbin/mysqld: ready for connections
InnoDB: Assertion failure in thread 2031640 in file trx0trx.c line 178
InnoDB: We intentionally generate a memory trap.
InnoDB: Send a detailed bug report to [EMAIL PROTECTED]
mysqld got signal 11;
This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked agaist 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=33550336
record_buffer=131072
sort_buffer=3145720
max_used_connections=135
max_connections=400
threads_connected=57
It is possible that mysqld could use up to
key_buffer_size + (record_buffer + sort_buffer)*max_connections = 1312760 K
bytes of memory
Hope that's ok, if not, decrease some variables in the equation
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...
Stack range sanity check OK, backtrace follows:
0x806cf16
0x8251748
0x83267f0
0x80bb94f
Stack trace seems successful - bottom reached
Please read http://www.mysql.com/doc/U/s/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
Trying to get some variables.
Some pointers may be invalid and cause the dump to abort...
thd->query at (nil) is invalid pointer
thd->thread_id=1976
Successfully dumped variables, if you ran with --log, take a look at the
details of what thread 1976 did to cause the crash. In some cases of really
bad corruption, the values shown above may be invalid
The manual page at http://www.mysql.com/doc/C/r/Crashing.html contains
information that should help you find out what is causing the crash

It happens when i have heavy load on my web, i use "ab" (apache
