A patch for this bug has been committed. After review, it may be pushed to the relevant source trees for release in the next version. You can access the patch from: http://lists.mysql.com/commits/75229 2858 Luis Soares 2009-05-29 BUG#44938: Replication fails when optimizing a table used by pending transaction. The original version of rpl_failed_optimize checked that a failed optimize operation would not harm replication. It performed two checks: 1. Check that failed optimize operations due to timeout (in this case, because it is optimizing a currently used table in other session), will not harm replication. After patch for BUG#989 was pushed, the test hangs here, due to meta data locks - optimize will block on mdl lock instead of innodb lock, causing the test operations on the other session not to execute. Consequently, the entire test hangs. 2. Check that optimizing a non-existing table will not harm replication. Due to the change in behavior introduced by patch for BUG#989, this fix addresses the blocking issue by removing item 1. @ mysql-test/extra/rpl_tests/rpl_failed_optimize.test Removed the blocking part of the test that has become deprecated after a change in behavior introduced by patch for BUG#989. @ mysql-test/suite/rpl/r/rpl_failed_optimize.result Updated the result file. @ mysql-test/suite/rpl/t/disabled.def Reenabled the test case. @ mysql-test/suite/rpl/t/rpl_failed_optimize-master.opt This server option does not make sense anymore after removal in the test case of the concurrent optimize.

Documented bugfix in the 5.4.4 changelog as follows: Running OPTIMIZE TABLE from one connection on a table in use by a transaction executed by another connection caused the server to hang, and replication to fail. See also Bug #989.
