有時，磁盤空間不夠用了，可能要刪除幾個mysql-bin，其后果可能是造成mysql無法啟動。

如可能出現下面的提示：

1.140211 16:12:03 [Note] Recovering after a crash using mysql-bin
2.140211 16:12:03 [Note] Starting crash recovery...
3.140211 16:12:03 [Note] Crash recovery finished.
4.140211 16:12:03 - mysqld got signal 11 ;
5.This could be because you hit a bug. It is also possible that this binary
6.or one of the libraries it was linked against is corrupt, improperly built,
7.or misconfigured. This error can also be caused by malfunctioning hardware.
8.We will try our best to scrape up some info that will hopefully help diagnose
9.the problem, but since we have already crashed, something is definitely wrong
10.and this may fail.
11.
12.key_buffer_size=0
13.read_buffer_size=2097152
14.max_used_connections=0
15.max_connections=1500
16.threads_connected=0
17.It is possible that mysqld could use up to
18.key_buffer_size + (read_buffer_size + sort_buffer_size)*max_connections = 7680000 K
19.bytes of memory
20.Hope that's ok; if not, decrease some variables in the equation.

解決辦法是把mysql-index文件中多余的內容刪除即可

1.MICDBSTG01:root:/u02/mysql-5.0.67-aix5.3-powerpc-64bit/data>vi mysql-bin.index
