This looks like pulseaudio is running out of memory.
For Reference. man pulse-client.conf
I have other other games that produce the same mmap error.
Create and edit file ~/.config/pulse/client.conf
Add or modify line enable-shm=no
Restart wine and pulseaudio completely and run Skyrim again.
This is a workaround, or solution depending on how to look at it, for xaudio (FAudio) applications running out of memory since pulseaudio default shm buffer is 64M and FAudio likes to create lots of these.
This might cause sounds to bed delayed a little, depending on you setup. If it does then reenable shm and set shm-size-bytes= to something smaller (maybe 5M, and note that this value is in bytes).
thanks a lot. that worked like a charm. :-)
