HandlerSocket Make MySQLD got signal 11 Version: Percona-Server-5.1.58-12.9 mysql error log :

• 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=67108864 read_buffer_size=524288 max_used_connections=20 max_threads=1100 threads_connected=37 It is possible that mysqld could use up to key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 1203924 K bytes of memory Hope that's ok; if not, decrease some variables in the equation.

Trying to get some variables. Some pointers may be invalid and cause the dump to abort. Query ((nil)): is an invalid pointer Connection ID (thread ID): 17 Status: NOT_KILLED

how to repeat? don't know.

BTW: May be epoll lost some fd.

I had the same issue on Ubuntu Server 10.04.3 LTS x86_64 with Mysql 5.1.41-3ubuntu12.10

After running "INSTALL PLUGIN handlersocket SONAME 'handlersocket.so'", process mysqld crashed:

But, if remove all handlersocket config parameters from /etc/mysql/my.cnf ,the command "INSTALL PLUGIN handlersocket SONAME 'handlersocket.so'" is sucessfull.
