Procedure may be deleted improperly during master restarts resulting in 'Corrupt'

Good news! stack, Apache9, I may find the root cause of mysterious ‘Corrupted procedure’ or some procedures disappeared after master restarts(happens during ITBLL).
This is because during master restarts, we load procedures from the log, and builds the 'holdingCleanupTracker' according each log's tracker. We may mark a procedure in the oldest log as deleted if one log doesn't contain the procedure. This is Inappropriate since one log will not contain info of the log if this procedure was not updated during the time. We can only delete the procedure only if it is not in the global tracker, which have the whole picture.

trackerNode = tracker.lookupClosestNode(trackerNode, procId);
        if (trackerNode == null || !trackerNode.contains(procId) ||
          trackerNode.isModified(procId)) {
          // the procedure was removed or modified
          node.delete(procId);
        }

A test case(testProcedureShouldNotCleanOnLoad) shows cleanly how the corruption happened in the patch.
