Question : Problem: Bus error in shared memory

Hii
I am developing an application that uses posix shared memory to share some data between the different process.
It worked well for quite some days but then when i ran it again after a couple of days , it showed me bus error whenever i tried to fill the shared memory with data.
i wrote a number of different programs earlier for shared memory but i am not able to run a single program now and every program is giving the same bus error.
pls suggest some way to resolve this

Answer : Problem: Bus error in shared memory

Please test the memory, and replace kernel image first(update).
There are limits put on sizes of shared memory, but You should encounter SEGV not BUS.
Current limits can be found at /proc/sys/kernel/shm*
