Steam leaks file descriptors

Hirato commented 9 years ago

After running for approximately 48 hours, steam exhausts the 1024 file descriptors that distros allow a single application to open by default at a user level.

It subsequently then prints messages like the follows

[1210/203805:WARNING:ipc_channel_posix.cc(887)] Message needs unreceived descriptors channel:0xf91d6000 message-type:132748 header()->num_fds:1
[1210/223527:ERROR:renderer_main.cc(227)] Running without renderer sandbox
[1210/223530:WARNING:shared_memory_posix.cc(386)] Shared memory creation failed; out of file descriptors
[1210/223530:ERROR:host_shared_bitmap_manager.cc(122)] Cannot create shared memory buffer
[1210/223530:WARNING:shared_memory_posix.cc(386)] Shared memory creation failed; out of file descriptors

[1210/223530:WARNING:shared_memory_posix.cc(386)] Shared memory creation failed; out of file descriptors

Various functionality in steam breaks from this point on, notably web pages inside steam become highly corrupted, and steam may need to be forcefully killed to allow it to start afresh.

This looks like an issue with the Chromium code we make use of (see https://code.google.com/p/chromium/issues/detail?id=333996).

alfred-valve commented 9 years ago

I've implemented the same work around as the Chrome folk (upping the fd limit), and we will watch for a more complete fix from upstream.
