>Description:
after several days of perfect functioning, mysql hangs completely.

if i try to shut it down with mysqladmin shutdown i get:

mysqladmin: connect to server at 'localhost' failed
error: 'Can't connect to MySQL server on localhost (60)'
Check that mysqld is running on localhost and that the port is 3306.
You can check this by doing 'telnet localhost 3306'

i ktrace'd the mysqld and saw it stuck in an infinite loop doing
this:

 19359 mysqld   PSIG  SIGILL caught handler=0xb0f0c mask=0x0 code=0x1
 19359 mysqld   CALL  sigreturn(0x1e37c78)
 19359 mysqld   RET   sigreturn JUSTRETURN
 19359 mysqld   PSIG  SIGILL caught handler=0xb0f0c mask=0x0 code=0x1
 19359 mysqld   CALL  sigreturn(0x1e37c78)
 19359 mysqld   RET   sigreturn JUSTRETURN
 19359 mysqld   PSIG  SIGILL caught handler=0xb0f0c mask=0x0 code=0x1
 19359 mysqld   CALL  sigreturn(0x1e37c78)
 19359 mysqld   RET   sigreturn JUSTRETURN
 19359 mysqld   PSIG  SIGILL caught handler=0xb0f0c mask=0x0 code=0x1

i am starting mysql with the following command:

/usr/local/mysql-32214b/libexec/mysqld -Omax_connections=300 -Oback_log=25 
-Othread_stack=131072 -Otable_cache=128 --skip-thread-prior -l --datadir=/usr/local/var

>How-To-Repeat:
i don't know what triggers it, we have a dozen or so databases
with many tables encompassing millions of rows of data.  every
week or so, mysql just gets stuck in an unkillable loop.  i have
to kill -9 it which usually corrupts some tables.
