Something must be wrong. > I have recently seen the same thing with 4.0-STABLE and XF86-4.0. I found that I had to up both SHMSEG and SHMMAXPGS. Specifically, on each machine setting SHMSEG to 100 and SHMMAXPGS to 2048 did the trick. I think that besides using many separate shared memory segments, the segments themselves are somewhat large. Seeing as how XF86-4 is in everyone's future, is there any reason not to nip these sort of problems now and up increase the default values for SHMSEG and SHMMAXPGS? The amount of additional kernel memory required is negligable for modern systems.
