Postby seans888 » 20. February 2014 05:13


Just updated to the xampp 1.8.3. Upon running xampp control panel, apache started while mysql won't. Error message as follows:

11:56:30 AM [mysql] Status change detected: running
11:56:31 AM [mysql] Status change detected: stopped
11:56:31 AM [mysql] Error: MySQL shutdown unexpectedly.
11:56:31 AM [mysql] This may be due to a blocked port, missing dependencies,
11:56:31 AM [mysql] improper privileges, a crash, or a shutdown by another method.
11:56:31 AM [mysql] Press the Logs button to view error logs and check
11:56:31 AM [mysql] the Windows Event Viewer for more clues
11:56:31 AM [mysql] If you need more help, copy and post this
11:56:31 AM [mysql] entire log window on the forums

I shutdown my firewall but still the same...

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.

It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 133777 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...
