mysqlkiki

请问造成崩溃的原因。

错误日志如下：
-----------------------------

InnoDB: If the corrupt page is an index page

InnoDB: by dumping, dropping, and reimporting

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=33554432
read_buffer_size=8388608
max_used_connections=949
max_threads=151
threads_connected=32
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 1939154 K
bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

where mysqld died. If you see no messages after this, something went
terribly wrong...
