The Error Log
-------------

`mysqld' writes all errors to the stderr, which the `safe_mysqld'
script redirects to a file called `'hostname'.err'.  (On Windows,
`mysqld' writes this directly to `\mysql\data\mysql.err').

This contains information indicating when `mysqld' was started and
stopped and also any critical errors found when running.  If `mysqld'
dies unexpectedly and `safe_mysqld' needs to restart `mysqld',
`safe_mysqld' will write a `restarted mysqld' row in this file.  This
log also holds a warning if `mysqld' notices a table that needs to be
automatically checked or repaired.

On some operating systems, the error log will contain a stack trace for
where `mysqld' died. This can be used to find out where `mysqld' died.
Note: Using stack trace.
