Hi All,

Sorry forgot to mention subject in earlier message.

I am running normal mysql and I am trying to insert one entry in one database table.

The logs I am getting are as follows:-

Version: '5.1.38-community' socket: '/var/lib/mysql/mysql.sock' port: 3306 MySQL Community Server (GPL)
091218 5:26:56 - 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=8384512
read_buffer_size=131072
max_used_connections=1
max_threads=151
threads_connected=1
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 338299 K
bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

terribly wrong...

Some pointers may be invalid and cause the dump to abort...
thd->query at 0x1da1840 = Select * From mydb.mytbl
thd->thread_id=2
thd->killed=NOT_KILLED

I am unable to get the root coz for this crash. The insert statement is as follows :-
Insert into mydb.mytbl(ID, sub)Values (1, 'Hi This is a test msg');
Well I am unable to get trace the reason behind this. can anyone please assist me on this. I am not even able to debug the problem. I can reporduce it by issuing same insert statement.Also I am using concept of symlinks in mysql data directory.

Thanks in advance.
