mysqld got signal 11 - it's my fault but how do I fix it? I was copying the database tables from our production server to my dev machine, and in the middle of the transfer I found out users were being locked out of the system because the select had locked a table. So...in my hurry to get the process to stop, I stupidly killed the mysqld process on my dev server.  Now, when I try to restart the service, I get the error below in my mysqld.log. I'm assuming it's because the table file for the table I was writing to is corrupted, but how do I go about getting the service to start again?  I did try moving the table files out of the database directory, but that didn't work (and yes, I put them back after!

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=8384512
read_buffer_size=131072
max_used_connections=0
max_threads=151
thread_count=0
connection_count=0
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 337742 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...

After a bunch more googling, etc., I finally came upon the solution: http://notesonit.blogspot.hk/2013/05/innodb-unable-to-lock-ibdata1-error-11.html
