先日のVirus騒ぎに引き続き、今度はMySQL 5.0.83が異常停止しました。その影響で、Apache 2.2のerror.logもかなり肥大化。全てのWebアクセスに対してエラーが出力されてるからです。
原因は不明。う～む。帰宅して、MySQLのWindowsサービスを起動したら、正常に起動するし。
以下、MySQLのerror.log
090617 13:29:27 - mysqld got exception 0xc0000005 ;
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=134217728
read_buffer_size=131072
max_used_connections=5
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 = 348671 K
bytes of memory
Hope that’s ok; if not, decrease some variables in the equation.thd=0325CDF0
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…
