- Hi:
- Subject kind of gives an idea, what the problem is. I am running a
- Client-Server model with shared memory and sockets. This runs smoothly until
- certain point, i.e., with a smaller problem size. Well, when I increase size
- of the problem my program dies, giving a message "Not enough memory on the
- device" (errorno is 28). I would expect that the problem is exceeding the Maximum
- size. We rebuild the kernel increasing the maximum limit to 3Meg. But it still
- dies. Can anyone please let me what's that I am missing? Am I (ie., My Sys Admin)
- building the kernel properly? Please e-mail any comments or suggestions. When
- does memory swapping come into picture?
- Thanks.
-
- P.S: I am running this on SUNOS 4.1, SUN 4/110 workstations. When I do vmstat it
- shows more than 3Meg of free memory. And a fast question: How can one get BUS
- alignment error (through xdbx) through malloc. My sequential
- version of the above Client-Server model gives that message, but doesn't
- return a NULL.
