mysqld坠毁"UTC - mysqld得到信号11"

在我的CentOS版本5.10(最终版),内核版本:Linux 2.6.18-371.6.1.el5#1 SMP Wed Mar 12 20:08:05 EDT 2014 i686 i686 i386 GNU/Linux,我有mysql版本mysql-5.6. 17-4.el5.我的mysqld在"service mysqld start"之后崩溃,日志中出现错误.能否请你帮忙:

2014-04-24 07:46:00 24175 [Note] Server hostname (bind-address): '*'; port: 3306
2014-04-24 07:46:00 24175 [Note] IPv6 is available.
2014-04-24 07:46:00 24175 [Note]   - '::' resolves to '::';

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=131072
max_used_connections=0
max_threads=500
thread_count=0
connection_count=0
It is possible that mysqld could use up to 
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 229484 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...
