What do you mean "persistent connection" ?
Persistent PHP connections ?

It doesn't crash for me when I use mysql command line client.
What MySQL client do you use - PHP ?

Could you please post a resolved stack trace as suggests the url above ?

Bug on MYSQL-5.0 in statement "OPTIMIZE TABLE"

2004-02-23 Thread Gelu Gogancea
Title: Bug on MYSQL-5.0 in statement "OPTIMIZE TABLE"






Hi,

TABLE CREATE DESCRIPTION :

CREATE TABLE T1(IDAP INT(16),TVAL INT(2),CH_VAL_SEC INT(16),INDEX(IDAP),INDEX(TVAL),INDEX(CH_VAL_SEC));


RUNNING CONDITIONS:

-use persistent connection.


RUNNING SEQUENCE:

1-Open 1-st connection.

2-insert in table many values at once time with "delayed" option;

"insert delayed into T1 (IDAP,TVAL,CH_VAL_SEC) VALUES(1,-2,100),(2,-3,101),(3,-4,102);"

3-I let 1-st connection open.Open 2-nd connection to execute the  next 2 statement.

4-delete all data from table :

"delete from T1;"

5-optimize the table :

"optimize table T1;"

MySQL daemon crash on this last statement if i use PERSISTENT CONNECTION, otherwise is OK.

From the mysql daemon log:


040223 14:59:49  mysqld started

040223 14:59:50  InnoDB: Started; log sequence number 0 43634

040223 14:59:50  /mysql/mysql-5.0.bin/libexec/mysqld: Can't create/write to file '/var/run/mysqld/mysqld.pid' (Errcode: 2)

040223 14:59:50  Found 4.1 style password for user '[EMAIL PROTECTED]'. Ignoring user. You should change password for this user.

/mysql/mysql-5.0.bin/libexec/mysqld: ready for connections.

Version: '5.0.0-alpha'  socket: '/mysql/mydatabase/mysql.sock'  port: 3306

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=2

max_connections=100

threads_connected=3

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=0x85b00a8

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=0x41da4ee4, backtrace may not be correct.

Stack range sanity check OK, backtrace follows:

0x813c7c4

0x4004e618

0x40049dea

0x4202726c

0x40049dea

0x8185301

0x400492b6

0x420de407

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

Trying to get some variables.

Some pointers may be invalid and cause the dump to abort...

thd->query at 0x8584920 = O.H..B.

thd->thread_id=4

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.
