Hi,
We are developing PBX based on Linux and we are using RTLINUX V1.
We are using shared memory , rt-fifos ,rt-ipcs, semaphores and message
queues for IPC.When a phone goes off hook the driver senses it
and a task is created using clone and the flow is as follows
Activate()
.. call processing
(wait using msgrcv)
Deactivate()
Now the problem is sometimes under load the process exits before
deactivation.
We have given handlers for all signals but no message is displayed.
Is there any way to find the cause of exit of a process?
We have increased MSGMNI to 2048 (more than max specified) and decreased
MSGMNB to 4056 in msg.h. Will it cause any problem?
Thank you
Prasad
