Yeah.... i tried to change the Page size to 16k, Other than rebooting again and agian.. machine did not do much :( Then i kept default pagesize and increased the Max shared segment size to 8Gb with maximum of 16 segments. i was able to get shmid of 15 segments of 8GB (by shmget) but when i attached the shared memory to two different process (by shmat) and then tried to write on the segment i got Segmentation fault. I also noticed that i cud not telnet to the machine. So, is it so ....... that i cannot have shared memory segments of 8gb ?? Vishal. > -- Kernelnewbies: Help each other learn about the Linux kernel.
