Title:
Java segfaulted in i965 driver - lots of deleted mmapped files
Status in xorg package in Ubuntu:
Incomplete
Bug description:
Java encountered a segfault in the i965 driver while running
Minecraft. A perusal of the dump report suggests that the issue is not
due to Minecraft but due to heavy use of the graphics exacerbating a
memory mapping leak in the driver - it seems that the mappings for
/dev/drm/card0 and /dri objects are not properly freed.
Note that I was running Optifine with Multi-Core loading, which causes
multi-threaded use of the graphics driver.
Important parts of the hs_err file are pasted below. However, I cut
out a *lot* of the /drm mm object and /dev/dri/card0 mappings. There's
a more than a hundred pages at 30 lines a page.

(normal library mappings follow, interspersed with more /dev/dri/card0
and /drm mm object (deleted) mappings)
From the crash log, I think it's evident that the driver is leaking
memory mappings.
