This is a synchronous IPC send of PluginMsg_CreateInstance (frame 9). Here's some stuff I logged in that renderer process before everything went to hell: pid 58027 channel 58037.r17 sends hello on pipe 25 pid 58027 channel 58037.r17 closes pipe 25 pid 58027 channel 58037.r17 sends hello on pipe 3 The renderer (58027) is closing fd 25 because IPC::Channel::ChannelImpl::ProcessIncomingMessages is hitting the | bytes_read == 0| case. This gets back to Channel::ChannelImpl::OnFileCanReadWithoutBlocking, which calls Close() because ProcessIncomingMessages returned false. -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
