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

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.
