It only took me 45 min to have X crash 2.4.0-test8-vm3, It occurred when i opened and closed xawtv a few times while the system was under stress from other apps (~1 load ) ... the shm segments kept increasing and i noticed something strange.
------ Semaphore Status -------- used arrays = 1 allocated semaphores = 14
It's always been 0 with the previous tests and with this test9-pre6 kernel. Not sure what the significance of it is.
SHM segments are increasing (they only go away when X closes) .. swap seems to be stable for now here is the ipcs -u output
------ Shared Memory Status -------- segments allocated 1379 pages allocated 8770 pages resident 8329 pages swapped 0 Swap performance: 2956 attempts 0 successes
------ Semaphore Status -------- used arrays = 0 allocated semaphores = 0
------ Messages: Status -------- allocated queues = 0 used headers = 0 used space = 0 bytes
I'm not sure how that swap performance is supposed to be, i need someone to compare to that has this stuff working and does not have the SHM problem ... i expect to crash within an hour.
