CEF crashes - broker pipe

Postby lolovo » Fri Sep 01, 2017 3:19 am

Hi everyone!

After some time of work in Release/Debug there is the following error after which program is crashed:
Code: Select all
[0901/101618.110:ERROR:broker_win.cc(59)] Error reading broker pipe: The pipe has been ended. (0x6D)
[0901/101618.110:ERROR:broker_win.cc(59)] Error reading broker pipe: The pipe has been ended. (0x6D)
[0901/101618.115:WARNING:child_thread_impl.cc(695)] Browser failed to allocate shared memory


Proxy (SOCKS) is used, so the question is - is this error related to this proxy SOCKS connection?

P.S. CEF3.2987.1601.gf035232_windows32

This issue is related to my post about shared memory Purge errors - http://www.magpcss.org/ceforum/viewtopic.php?f=6&t=14737

It seems like synergistic effect when non of shared memory was released by VirtualFree in Purge.

I have the same problem for over a year now. (I kept trying with every new CEF release/update)
It occurs to me when using the Flash Plugin and I think it has something to do with a leak due to unreleased memory when exchanging data between the renderer process and plugin process.

For example the memory keeps increasing until the crash when you open the flash plugin and run the flash stress test from here: http://blog.bwhiting.co.uk/?p=314

It's always the renderer process that keeps crashing, not the plugin process.

Code: Select all
[0607/151317.559:WARNING:child_thread_impl.cc(734)] Browser failed to allocate shared memory


When using the command line switch "--single-process" then this problem doesn't occur.

Also an unrelated bug: When using the flash plugin with the --single-process flag, it crashes upon start. That happens since CEF-3359
