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.
Attempting to collect some information that could help diagnose the problem.
As this is a crash and something is definitely wrong, the information
collection process might fail.
key_buffer_size=1073741824
read_buffer_size=2097152
max_used_connections=158
max_threads=200
thread_count=72
connection_count=70
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 2280160 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...

The manual page at
http://dev.mysql.com/doc/mysql/en/crashing.html contains
information that should help you find out what is causing the crash.
no error message before that
what can I do or how to debug that?
thanks
