WebContent process: HTMLMediaElement changes state (canProduceAudioChanged) MediaSessionManagerCocoa sets the category of RemoteAudioSession, which sends an IPC message(RemoteAudioSessionProxy::SetCategory) to the GPU Process. GPU Process: 3. RemoteAudioSessionProxy starts the process to set the category of AudioSessionMac, which will call LocalAudioSessionRoutingArbitrator to send an IPC message (GPUProcessConnection::BeginRoutingArbitrationWithCategory) to the WebContent process. WebContent Process: 4. Send an IPC message (AudioSessionRoutingArbitratorProxy::BeginRoutingArbitrationWithCategory) to the UI process. UI Process: 5. Call SharedRoutingArbitrator::beginRoutingArbitrationWithCategoryForToken(). After the GPU Process crashes, WebContent Process: 6. Reload and resume the media playback. This will lead to the state change in step 1, after that step 2, 3, 4, 5 will run again. UI Process: 7. Clean up routing arbitrator by calling SharedRoutingArbitrator::endRoutingArbitrationForToken(). Normally, step 6 and 7 happen almost at the same time (in different processes). Step 7 will be done before steps 1, 2, 3, 4, and 5 which are triggered by step 6. However, that is not guaranteed. If step 7 is delayed for some reason, step 5 will crash with an assertion failure. 1776532 4 ap 2021-07-12 19:45:04 -0700 This keeps happening super frequently, roughly half of the time.

I think it is a good idea to disable the test for now. 1778567 6 433960 peng.liu6 2021-07-21 14:49:11 -0700 Created attachment 433960 Patch 1778741 7 ews-feeder 2021-07-22 10:29:06 -0700 Committed r280180 (239874@main): <https://commits.webkit.org/239874@main> All reviewed patches have been landed.
