The problem was a race condition on shutdown -- when IM got shutdown request while a guarded mysqld is starting. In this case the Guardian thread tried to stop the mysqld, but might fail if the mysqld hadn't created pid-file so far. When this happened, the mysqld-monitor thread didn't stop, so the assert in Thread_registry happened. The fix is to make several attempts to stop mysqld if it is active. server-tools/instance-manager/guardian.cc: Try to stop mysqld several times if it is still active. server-tools/instance-manager/instance.cc: Make Instance::kill_mysqld() to return operation status. server-tools/instance-manager/instance.h: Make Instance::kill_mysqld() to return operation status. server-tools/instance-manager/thread_registry.cc: Log unregistered thread ids. |
