Environment:
I'm setting up a database server on a Dell Poweredge 2650, dual 1.8GHZ pentium
with 1GB of memory and RAID5 drives. I've installed RedHat 9, and updated the
kernel to 2.4.20-19.9smp. I've installed the RPM binary distribution of MySQL
4.0.14 right from the MySQL website. The only thing I have done is disable
InnoDb in my my.cnf file.
Database Table:
I have a database with 21.4 million records. One field is a VARCHAR(255) field
on which I have created a FULLTEXT index.
Problem:
Most single word full text searches work perfectly and quickly. Occasionally,
when someone enters several words (without any operators), MySQL will crash
with the following in the error log (see below). This is totally consistent,
and MySQL will crash on the same submitted search text each time. Then other,
more complex terms will work. But I can make MySQL crash every time with the
query below in the error log. I've already rebuilt the fulltext index with
myisamchk, and there are no writes to this table at all - it's totally read
only.
I'm not sure what to do next - I don't want to have my database crashing every
hour when someone submits a valid search term that trips up the database.
Any help would be most appreciated.
Thanks,
-Hank

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=3
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...

Please read http://www.mysql.com/doc/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
