centos + php 4 + mysql 4 + apache 1.x 版已經運作3年沒有錯誤,今天突然mysql
不斷重啟,在網路上也找個無數的資料仍舊無法解決(如調參數等),也重灌過MSYQL
一樣會重啟.
錯誤訊息如下
Number of processes running now: 0
091216 21:40:18 mysqld restarted
/usr/sbin/mysqld: ready for connections.
Version: '4.0.27-standard' socket: '/var/lib/mysql/mysql.sock' port: 3306

mysqld got signal 11;
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=16777216
read_buffer_size=258048
max_used_connections=0
max_connections=500
threads_connected=1
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_connections =
398380 K
bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

thd=0x8433430
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=0xbf5fdc78, backtrace may not be correct.
Stack range sanity check OK, backtrace follows:
0x8096421
0x82aa0d0

New value of fp=(nil) failed sanity check, terminating stack trace!
Please read http://dev.mysql.com/doc/mysql/en/Using_stack_trace.html and
follow instructions on how to resolve the stack trace. Resolved
stack trace is much more helpful in diagnosing the problem, so please do
resolve it
Trying to get some variables.
Some pointers may be invalid and cause the dump to abort...
thd->query at 0x8482d60 =

The manual page at http://www.mysql.com/doc/en/Crashing.html contains
information that should help you find out what is causing the crash.
