PS. I now get this in the mysqld.err log after server shutdown in PBXT test suite:
091124 13:09:45 [Warning] Plugin 'MyISAM' will be forced to shutdown 091124 13:09:45 [Warning] Plugin 'PBXT' will be forced to shutdown
Ok, some more details: I can repeat this by running an empty test case (mysql-test/suite/pbxt/t/kn.test): ------------------------------ cut here ------------------------------ --skip "Test shutdown problem with skipped test" ------------------------------ cut here ------------------------------ (cd mysql-test && perl mysql-test-run.pl --suite=pbxt pbxt.kn) I get this in the mysqld.1.err: CURRENT_TEST: pbxt.kn 091124 15:11:00 [Note] Plugin 'InnoDB' is disabled. 091124 15:11:00 [Note] PrimeBase XT (PBXT) Engine 1.0.08d RC loaded... 091124 15:11:00 [Note] Paul McCullagh, PrimeBase Technologies GmbH, http://www.primebase.org 091124 15:11:00 [Note] Event Scheduler: Loaded 0 events 091124 15:11:00 [Note] /home/knielsen/devel/maria/my/merge-5.1.41/sql/mysqld: ready for connections.

Maybe this is another problem with the way that PBXT has to do init in a separate thread, I see you already had to solve some other possibly related problems. Any ideas? It may be that this is something introduced in the merge with MySQL 5.1.41, not 100% sure though as this particular warning was not detected before in our Buildbot tests... - Kristian.
