Hello everyone,
I have seen this message crop up recently when connections are
denied:
mysqladmin: connect to server at 'localhost' failed
error: 'Can't create a new thread (errno 12). If you are not out of
available me mory, you can consult the manual for a possible OS-dependent bug'
Unfortuantely, I haven't been able to find anything in the manual
relating to this or an OS bug. The server is running Debian 3.1,
mysql 4.0.23, with kernel 2.6.7.
I have the results of status and extended-status around the time of
the outages:

"The good Christian should beware of mathematicians, and all those who
make empty prophecies. The danger already exists that the mathematicians
have made a covenant with the devil to darken the spirit and to confine
man in the bonds of Hell."
--St. Augustine, De Genesi ad Litteram, Book II, xviii, 37
