从过去 4 天开始，我们面临着 mysql infobright 引擎频繁的数据库崩溃，生产环境最近没有变化，也没有更新。目前我们使用的是 5.1.40 版本。
找到下面的转储，任何人都可以帮助找出问题所在。

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=1677721600
read_buffer_size=1048576
max_used_connections=75
max_threads=1000
threads_connected=54
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 3696548 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...
