What does "lock" mean here? Does the whole box hang, does just the bridge stop to work, ...? Is there anything special necessary to trigger this issue? Is there anything that helps to recover from the issue?

"lock" means the bridge stop to work.
I do the following steps:
(1)Setup transparent wireless bridge network.
(2)PC1 and PC2 ping each other and the bridge work fine.
(3)Do not turn off AP and Station,and exchange PC1 and PC2.
(4)PC1 and PC2 ping each other and the bridge is locked.
(5)Restore PC1 and PC2 to the original place.
(6)PC1 and PC2 ping each other and the bridge is still locked.
(7)Turn off and then turn on the "ath0", the bridge is still locked.

I have found that when using the bridging code the ageing timer in the bridge may need to be adjusted otherwise you will have problems moving a pc from one end of the link to the other. I have not had a chance to completely verify this.
