--- Comment #11 from Miguel Gomez <magomez at igalia.com> ---
>From the logs, what I see is that the WebProcess starts devouring memory (like 6.5GB of VM), the Memory Pressure Handler is running constantly, and eventually the WebProcess gets killed by the oom killer. During this, the kernel fails several times to allocate memory for other tasks, like buffers for network packages and such.

This huge memory consumption is probably due to the threaded compositor, which was enabled in 2.13.4, and the fact that the accelerated compositing was enabled by default (with the extra memory consumption in mesa due to the usage of the software rasterizer).

This memory issue was greatly improved by returning to the on demand acc compositing and by using a higher opengl version (no more software rasterizer on mesa), together with other tweaks in garbage collection. The problem should not be reproducible using the latest 2.15 and 2.16 versions.

Can you verify this Andres? Should we close this?
