MySQL crasher, genstarter, og crasher igen

 

Hej SLLUG'er!

På vores produktions-site har vi i øjeblikket store problemer med MySQL
databasen. Serveropstillingen består af to servere, hvor den ene kører
Apache2 og den anden MySQL 4.0.15.

Apache-serveren kører upåklageligt - det samme kan man næppe sige om
MySQL'en.

Dette er min error log på et givent tidspunkt:

------------------------------------------------------------------------------
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=16777216
read_buffer_size=131072
max_used_connections=11
max_connections=100
threads_connected=2
It is possible that mysqld could use up to 
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_connections
= 233983 K
bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

thd=(nil)
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=0xbfff8038, backtrace may not be correct.
Stack range sanity check OK, backtrace follows:
0x80fb888
0x4013403c
0x4001d99e
0x4001ccf2
0x4001c3cb
0x4001c187
0x80fd88f
0x80fcdb9
0x402bd7a7
0x80ac751
New value of fp=(nil) failed sanity check, terminating stack trace!
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
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.

Number of processes running now: 0
031024 08:44:26  mysqld restarted
Warning: Ignoring user change to 'mysql' because the user was set to
'mysql' earlier o
n the command line
/usr/sbin/mysqld: ready for connections.
Version: '4.0.14'  socket: '/var/run/mysqld/mysqld.sock'  port: 3306
------------------------------------------------------------------------------

Dette sker ca. hvert 10. minut. Alle forslag til fejlfinding på denne
fejl er meget velkomne da jeg mildest talt er ved at være desperat!

Serveren kører Gentoo Linux.
Det er en Dual Pentium III


P.f.h Tak!
