1. You need to recompile your kernel after modifying msg.h file.
2. also try to see message size using /proc/sys/kernel/msgmax

This works fine for upto 6k packet size and beyond that the kernel crashes.
The error that it gives is kernel stack overflow and sometimes kernel
BUG in sched.c:915!.
Please mention the kernel version for this to make sense.
I am using linux-2.4.20
I also increased the MSGMNB and MSGMAX values in msg.h.
Could you please suggest how to go about in solving this problem?
