USE DATABASE mysql;
SET PASSWORD FOR root@localhost=PASSWORD(‘yournewpassword’);
FLUSH PRIVILEGES;

And voila! You have changed your password.

PS: If you have a “problem” with beeing able to login to MySQL without using password (even when it is set in MySQL), try to edit or delete ~/my.cnf, since that holds information used to avoid the login promt.

Callback called exit.” error in Request Tracker (RT) http://h3x.no/2009/04/17/fix-for-the-out-of-memory-callback-called-exit-error-in-request-tracker-rt http://h3x.no/2009/04/17/fix-for-the-out-of-memory-callback-called-exit-error-in-request-tracker-rt#comments Fri, 17 Apr 2009 13:54:32 +0000 Tor Henning Ueland http://www.h3x.no/?p=30 When RT is upgraded, users can experience WSOD(White Screen Of Death), all the log will say is:
“Out of memory! Callback called exit.”. Not so informative eh?

The solution is pretty simple, run this query in the database:

“ALTER TABLE sessions CHANGE a_session a_session LONGBLOB;”

Then clear the table with:

TRUNCATE TABLE `sessions`;

Any logged in users will be logged out, but the problem should disappear.
