On my machine (gentoo, 2.6.38 kernel, intel graphics, with drivers and Mesa from git) the problem manifests itself with: osgviewer: /var/tmp/portage/x11- libs/libX11-1.4.3/work/libX11-1.4.3/src/xcb_io.c:515: _XReply: Assertion `!dpy->xcb->reply_data' failed. Aborted Very occasionally I also got the the "Resource temporarily unavailable" error. I just tried Robert's suggestion, and osgviewer runs stable in single-threaded mode.
