My Producion-mysqlserver crashes reproducable running the EM64T code on a 4CPU-SMP System with 32 GB. 
The 32Bit-Version is much more stable.
The Message in mysql err-file is:
060306 17:26:55 [Note] /usr/sbin/mysqld: ready for connections.
Version: '5.0.18-standard'  socket: '/u/mysql/mysql.sock'  port: 3306  MySQL Com

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.

It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_connections = 466543 Kbytes of memory.

With 32Bit mysql-code the system is fast enough. So its "non-critical".

How to repeat:
I have no good idear howto reproduce this behaviour.
What I know: 
Simple statements (select field1 field2 ... from one_table) work. 
More compicated statement with more inner or outer joins tend to lead to a crash.
MS-Access SQL-Statement:

Thank you for a problem report. What exact version of our binaries do you use? Send also the EXPLAIN results for the query that tent to crash server on 64-bit.
[11 Mar 2006 12:32] [ name withheld ]
Version used so far:
mysqld  Ver 5.0.18-standard for unknown-linux-gnu on x86_64 (MySQL Community Edition - Standard (GPL))
Version used now:
mysqld --version: mysql  Ver 14.12 Distrib 5.0.18, for pc-linux-gnu (i686) using readline 5.0

Either running on:
SUSE LINUX Enterprise Server 9 (x86_64) - Kernel 2.6.5-7.252-smp (0).

I cannot tell about the "explained" statement now, because our "production server" runs the more stable 32Bit-Version now. And MS-Access's translation of  the Query through odbc is not obvious. The initial Query is broken down into many peaces.
I'll come back when we find a time slot to switch back to the buggy version and are able to analyse the exact behaviour. Or when a new 64-bit version is released at mysql.com.

By writing this, I recognise that there is 5.0.19.
[11 Mar 2006 13:28] [ name withheld ]
Version 5.0.19 seems to solve the issues.

I suggest u may close the call.

[13 Mar 2006 9:04] Valeriy Kravchuk
Closed as the problem seems solved in 5.0.19
