Description:
we have large numbers of tables:
database : 18+1
tables : 18*198(10 partitions every table) + 1*301.
every day there will generator about 5G data.

question1: open tables too many.
beacause of my query need scan 198 tables every time, so we need to flush table when i query 10 tables, else there will errors.

queston 2: table crash.
sometimes we have a lot of crashed tables.
how can i repair these crashed tables automatical ?, how can i find these crashed table ?  

thanks!

How to repeat:
when i do large numbers of query and insert.and then i must to flush table.

Suggested fix:
fush table to lead to some errors ?  if can not flush table what can i do?

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=402653184
read_buffer_size=2097152
max_used_connections=8
max_threads=151
threads_connected=7
It is possible that mysqld could use up to 
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 1012664 K
bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

Do you have the same problem on both Windows and Linux? Please, check with a newer version, 5.1.41, and, in case of the same problems, upload your my.cnf/my.ini file content.

thank you very much ! i am sorry to receive you email too latter!
now we use it in windows,we will subordinate it to linux!

# This is for a large system with memory of 1G-2G where the system runs mainly

# server-id	= 1

# Replication Slave (comment out master section to use this)
#
# To configure this host as a replication slave, you can choose between
# two methods :
#
# 1) Use the CHANGE MASTER TO command (fully described in our manual) -
#    the syntax is:
#
#    CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>,
#    MASTER_USER=<user>, MASTER_PASSWORD=<password> ;
#
#    where you replace <host>, <user>, <password> by quoted strings and
#    <port> by the master's port number (3306 by default).
#
#    Example:
#
#    CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306,
#    MASTER_USER='joe', MASTER_PASSWORD='secret';
#
# OR
#
# 2) Set the variables below. However, in case you choose this method, then
#    start replication for the first time (even unsuccessfully, for example
#    if you mistyped the password in master-password and the slave fails to
#    connect), the slave will create a master.info file, and any later
#    change in this file to the variables' values below will be ignored and
#    overridden by the content of the master.info file, unless you shutdown
#    the slave server, delete master.info and restart the slaver server.
#    For that reason, you may want to leave the lines below untouched
#    (commented) and instead use CHANGE MASTER TO (see above)
#
# required unique id between 2 and 2^32 - 1
# (and different from the master)
# defaults to 2 if master-host is set
# but will not function as a slave if omitted
#server-id       = 2
#
# The replication master for this slave - required
#master-host     =   <hostname>
#
# The username the slave will use for authentication when connecting
# to the master - required
#master-user     =   <username>
#
# The password the slave will authenticate with when connecting to
# the master - required
#master-password =   <password>
#
# The port the master is listening on.
# optional - defaults to 3306
#master-port     =  <port>
#
# binary logging - not required for slaves, but recommended
#log-bin=mysql-bin

Thank you for the feedback.

Please try current version 5.1.41 (or better upcoming 5.1.42 with fix for bug #46676): we have several bugs related to concurrent operations and FLUSH TABLES fixed lately. If problem still exists please provide output of SHOW CREATE TABLE for some of your partitioned tables.
