Re: Msg Q for user <-> kernel space

[jyothi <jyothi@xxxxxxxxxxxxxx>]

We are using message queue interface for sending messages from kernel to
user space and vice versa.
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?
