lost connection to mysql server during query

HI

I’m running mysql stored procedure using VB as front end. While clicking Ok button in application it calls 3 stored procedures and returns a resultset. First time it works properly. If second time clicked the error ‘lost connection to mysql server during query’ displayed. Third time works fine. Like this alternatively throws error message.

Any one explain What is the reason for this error ‘lost connection to mysql server during query’

While throwing ‘lost connection to mysql error during query’ following are entries in mysqld.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=8388600
read_buffer_size=131072
max_used_connections=1
max_connections=100
threads_connected=1
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_connections = 225791 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…
Cannot determine thread, fp=0xb4bc9f48, backtrace may not be correct.

Please read http://dev.mysql.com/doc/mysql/en/Using_stack_trace.html and follow instructions on how to resolve the stack trace. Resolved
stack trace is much more helpful in diagnosing the problem, so please do
resolve it
