мускуль сдох...

mysql-4.0.22 внезапно перестал отбивать запросы....
Ну, думаю, подвисло че-нить, с кем не бывает?..

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=0
max_connections=100
threads_connected=0
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=0x82fc3e8
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...
Bogus stack limit or frame pointer, fp=0xbfffeaf8, stack_bottom=0x56555453, thread_stack=131072, aborting backtrace.
Trying to get some variables.
Some pointers may be invalid and cause the dump to abort...
thd->query at 0x5251504f is invalid pointer
thd->thread_id=0



Cовершенно непонятно, в общем, к чему ему пермишен денайд, и чего вообще случилось - вчера еще работало все....

Заранее спасибо всем за ответы.
