mysqldump
在MySQL 5.0.16上，用mysqldump导出数据，mysqldump半天没反应。
操作系统是RHEL4.0。

mysqld got signal 6;
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=8388600
read_buffer_size=131072
max_used_connections=2
max_connections=100
threads_connected=2
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_connections = 225791 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...
Cannot determine thread, fp=0xb17d5a6c, backtrace may not be correct.
Stack range sanity check OK, backtrace follows:
0x815f652
0x9ed7c8
