[Comm] Падает MySQL

[Pavel Stoliarov <mylinux02@mail.ru>]

Система  Compact 3.0

Иногда MySQL падает :

Version: '5.0.22'  socket: '/mysql.sock'  port: 3306  ALT Linux MySQL RPM
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=53
max_connections=100
threads_connected=35
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.
                                                                                                               

thd=0xb53a5290
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...
frame pointer (ebp) is NULL, did you compile with
-fomit-frame-pointer? Aborting backtrace!
Trying to get some variables.
Some pointers may be invalid and cause the dump to abort...
thd->query at 0xb3d134b8  is invalid pointer
thd->thread_id=2075
The manual page at http://www.mysql.com/doc/en/Crashing.html contains
information that should help you find out what is causing the crash.
2006-Jul-06 00:50:13 :: execution failed
2006-Jul-06 00:50:13 :: shutdown

Советы , приведеные в вышеуказаной ссылке по тестированию и оптимизации 
базы итд,
к успеху не привели.

Может быть mysql 5.0.x еще сыровата ?
Есть смысл откатиться на 4.1.x ?
